Adding or Deleting Rows and Columns from Tables
I have notices that you can't delete or add a row or columns from a table in iWeb without having problems.
You may get two added or deleted.
I should indicate that the table comes from Excel.
Does anyone know of a work-around?
Problem 1 - The sub-form 'Stds' was not configured for repeating rows.
Problem 2 - The script was on the wrong event. The script should be on the 'change' event and not the 'initialize' event.
Problem 3 - Which header row in which sub-form are you referring too?

Remove specific row and column from 2d array
Hi,
I would like to know how to remove the specific row and column from 2d array.
for example, I have the original 4x4 array as below
2 -1 -1 0
-1 2 0 -1
-1 -1 2 0
-1 -1 -1 3
let say that i want to remove row 2(bold) and column 2(bold), and the new 2d array should get as below
2 -1 0
-1 2 -1
-1 -1 3
Thanks.You can't remove elements of an array, it's fixed at a certain size once created. What you can do however is make a new array and only copy the things you want. Something like:public static void main(String[] args) {
Integer[][] bar = new Integer[5][5];
for (int i = 0; i < bar.length; i++) {
Integer[] baz = bar;
Arrays.fill(baz, i);
System.out.println(Arrays.toString(baz));
Integer[][] muu = new Integer[5][4];
removeColumn(3, bar, muu);
for (Integer[] mee : muu) {
System.out.println(Arrays.toString(mee));
Integer[][] smuu = new Integer[4][5];
removeRow(3, bar, smuu);
for (Integer[] mee : smuu) {
System.out.println(Arrays.toString(mee));
public static <T> void removeRow(int row, T[][] a, T[][] result) {
if (row >= a.length) {
throw new IllegalArgumentException("no row at " + row);
for (int a_r = 0, result_r = 0; a_r < a.length; a_r++) {
if (a_r == row) {
continue;
System.arraycopy(a[a_r], 0, result[result_r], 0, a[a_r].length);
result_r++;
public static <T> void removeColumn(int col, T[][] a, T[][] result) {
for (int i = 0; i < a.length; i++) {
if (col >= a[i].length) {
throw new IllegalArgumentException("no column at [" + i + ", " + col + "]");
for (int a_i = 0, r_i = 0; a_i < a[i].length; a_i++) {
if (a_i == col) {
continue;
result[i][r_i] = a[i][a_i];
r_i++; -
Select row and column from header in jtable
hello i have a problem to select row and column from header in jtable..
can somebody give me an idea on how to write the program on it.Hi Vicky Liu,
Thank you for your reply. I'm sorry for not clear question.
Answer for your question:
1. First value of Open is item fiels in Dataset2 and this value only for first month (january). But for other month Open value get from Close in previous month.
* I have 2 Dataset , Dataset1 is all data for show in my report. Dataset2 is only first Open for first month
2. the picture for detail of my report
Detail for Red number:
1. tb_Open -> tb_Close in previous month but first month from item field in Dataset2
espression =FormatNumber(Code.GetOpening(Fields!month.Value,First(Fields!open.Value, "Dataset2")))
2. tb_TOTAL1 group on item_part = 1
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)))
3. tb_TOTAL2 group on item_part = 3 or item_part = 4
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)) + ReportItems!tb_TOTAL1.Value )
4. tb_TOTAL3 group on item_part = 2
expression =FormatNumber(Sum(CDbl(Fields!budget.Value)) - ReportItems!tb_TOTAL2 .Value)
5. tb_Close -> calculate from tb_TOTAL3 - tb_Open
expression =FormatNumber(Code.GetClosing(ReportItems!tb_TOTAL3.Value,ReportItems!tb_Open.Value))
I want to calculate the value of tb_Open and tb_Close. I try to use custom code for calculate them. tb_close is correct but tb_Open is not correct that show value = 0 .
My custom code:
Dim Shared prev_close As Double
Dim Shared now_close As Double
Dim Shared now_open As Double
Public Function GetClosing(TOTAL3 as Double,NowOpening as Double)
now_close = TOTAL3 + NowOpening
prev_close = now_close
Return now_close
End Function
Public Function GetOpening(Month as String,NowOpen as Double)
If Month = "1" Then
now_open = NowOpen
Else
now_open = prev_close
End If
Return now_open
End Function
Thanks alot for your help!

ALV grid oo delete rows and update to table
Hi all
How can I delete one row and update to the db table?
thanksHi,
Refer:-
The ALV Grid has events data_changed and data_changed_finished. The former method is
triggered just after the change at an editable field is perceived. Here you can make checks for
the input. And the second event is triggered after the change is committed.
You can select the way how the control perceives data changes by using the method
register_edit_event. You have two choices:
1. After return key is pressed: To select this way, to the parameter i_event_id pass cl_gui_alv_grid=>mc_evt_enter.
2. After the field is modified and the cursor is moved to another field: For this, pass cl_gui_alv_grid=>mc_evt_modifies to the same parameter.
To make events controlling data changes be triggered, you must select either way by
calling this method. Otherwise, these events will not be triggered.
To control field data changes, ALV Grid uses an instance of the class
CL_ALV_CHANGED_DATA_PROTOCOL and passes this via the event data_changed.
Using methods of this class, you can get and modify cell values and produce error messages.
Hope this helps you.

Importing rows and columns from Excel to Cluster and Array in Labview
An excel table consist of 4 columns and variable number of rows, the first column is the position number and the other 3 columns are series of coordinates (X,Y,Z). I would like to import the excel table into Labview such that each row in the table will form a cluster which consist of the position number and the coordinates of each position and each formed cluster should converted to a 1D-Array(double).
I would be glad if someone can tell me the best way to go about this or better still show me some examples because i am very new in Labview.
Thanks
OmobaThe easy way would be to save the excel file as csv (colon seperated values) and load it into ascii via load spreadsheet file (use ; as delimiter).
The more advanced way is to interface excel via ActiveX. Use the example finder and search for ActiveX to find some examples that interface excel (they should be shipped with LabVIEW).
Post back if you have more detailed questions.

Dynamic Table - Add rows and columns in same table
Hi there,
I wonder if someone could help please? I'm trying to create and table where a user can add both rows and columns (preferably with separate buttons) but am having trouble trying to figure out how to do this. Is it possible? If so how? I'm not familar with script but have found examples of seprate tables where you can add a row and then another table where you can add columns and essentailly want to merge the two but cannot make it work.
Any help much appreciated!
Thanks,
KenIt is great example....you can learn the concepts there and apply....however you may have to think twice before you implement column adding dynamically....because the technique here is make copy of what we already have and reproduce it as a new item and this technique works great for rows as they all have every thing in common. But when it comes to columns it may have unique visible identity as column head and displaying repeatedly the same column head may not look good. Of-Course you can do few extra lines of code and change the column appearance based on users input each time. Situations where users need to add additional column is very unlikely (sure your requirement might be an exception).
Key in allowing adding/removing instances is managing design mode settings under Object>>Binding>>....and select the checkbox "Repeat <subform/row/...> for Each Data Item" and then set Min, Max and Initial count values.
Also you need to club your effots by using simple scipt with button clicks....
for the example refered in URL you posted following is what I did to make the first table allow Adding/Removing Rows....
1. Opened the form in LC designer.
2. Add two buttons AddRow & RemoveRow right next to RemoveColumn
3. For AddRow I used following JS code....
Table1._Row1.addInstance(1);//that means any time this button is clicked a new instance of Row1 is added use _Row2 or Row3 based on your needs
var fVersion = new Number(xfa.host.version); // this will be a floating point number like "7.05"
if (fVersion < 8.0) // do this for Acrobat versions earlier than 8.0
// make sure that the new instance is properly rendered
xfa.layout.relayout();
4. For RemoveRow I used following JS code....
Table1._Row1.removeInstance(1);//Syntax is...<objectReference>.removeInstance(<index of the repeating object that needs to be removed>); //in this case since we used 1 alwasys second object from top gets deleted.
var fVersion = new Number(xfa.host.version); // this will be a floating point number like "7.05"
if (fVersion < 8.0) // do this for Acrobat versions earlier than 8.0
// make sure that the new instance is properly rendered
xfa.layout.relayout();
5. Now time to update settings at Object>>Binding tab and set "Repeat......" and also set Min, Max and Initial count as explained above.
Those settings needs to be updated for Row1 (or your choice of row) of the table
6. Set the Height to Expand of the Subform, where the table is housed.... this is done under Layout pallet
7. Save the PDF as dynamic template and verify the results...
If you still run into issues I can send you copy that works on my machine, but you need send me an email at n_varma(AT)lycos.com
Good luck, -
how can i open a PDF bank statement in "numbers" so that the rows and columns contain properly aligned data from statement?
Numbers can store pdfs pages or clippings but does not directly open pdf files. To get the bank statement into Numbers as a table I would open the bank statment in Preview (or Skim) or some pdf viewer.
Then hold the option key while selecting a column of data.
Then copy
Then switch to numbers and paste the column into a table
Then repeat for the other columns in the pdf document
It would be easier (in my opinion) to download the QFX or CSV version from your bank -
How do I delete multiple rows and columns in an image?
I am looking into how digital SLRs extract video data from a CMOS sensor. To give an example, the GH1 from Panasonic can record video at 1920 x 1080 from a 12 MPixel sensor that, say, is 4000 horizontal x 3000 vertical. How they do that seems to be not in the public domain, but there have been a few guesses (see http://www.dvxuser.com/V6/showthread.php?t=206797 and http://luminous-landscape.com/forum/index.php?showtopic=38713).
One approach would be to simply read every second row of sensor pixels (1500 rows read from the original 3000) and once you have those in memory, delete every second column (2000 columns left). You would end up with a 2000 x 1500 image which could then be resampled to 1920 x 1080.
I'd like to simulate what the camera appears to be doing, by generating a 4000 x 3000 test image and then asking Photoshop CS4 to delete the appropriate rows and columns. It may not necessarily be every second row; the Canon 5DMk11 appears to read every third row, so I may need to delete two out of every three rows.
Can Photoshop do that sort of thing? If so, how?Thanks for the suggestions. Yes, I did take a detailed look at your images, but they weren't 100% convincing because it wasn't clear just what was happening. And Adobe's explanation, after reading it again, explains nothing at all to someone who doesn't know how Nearest Neighbor works.
But you are correct -- Nearest Neighbor does effectively delete pixels. I proved it with the attached 6 x 6 image of coloured pixels (the tiny midget image right after this full stop -- you'll have to go to maximum zoom in PS to see it).
These are the steps to delete every second row and then every second column.
1. Select Image > Image Size.
2. Set Pixel Dimensions > Height to half the original (in this case set to 3 pixels).
3. Set Resample Image to Nearest Neighbor.
4. Click OK and the image shoould now consist of three vertical white strips and three vertical Green-Red-Blue stripes.
5. Repeat steps 1-4, but this time set Pixel Dimensions > Width to half the original (in this case set to 3 pixels). The image should now consist of three horizontal stripes Green-Red-Blue.
Just to make sure the method worked for every third pixel, I repeated the above steps but with 2 pixels instead of 3 and obtained the correct White-Green, White-Green pattern.
I resampled the Height and Width separately for the test so that I could see what was happening. In a real example, the height and width can be changed at the same time in the one step, achieving the same results as above.
Finally, how to explain how Nearest Neighbor works in the simple cases described above?
Division by 2
In the case of an exact division by two (pixels numbered from top leftmost pixel), only the even numbered rows and columns remain. To put it a different way, every odd numbered row and column are deleted.
Division by 3
Only rows and columns 2, 5, 8, 11... remain.
Division by N
Only rows and columns 2, 2+N, 2+2N, 2+3N... remain.
To put it simply, a resample using Nearest Neighbor (using an exact integer multiple) keeps every Nth row and column, starting from number two. The rest are deleted. -

Table -- sum of rows and columns?
I was wondering if anyone has a suggestion to how I can easily generate the sum of each row and column in a two dimensional table? This is what I've got so far:
public class SumRowsColumns {
public static void main (String[] args) {
int[][] table = new int[2][3];
// gets the values
for (int i = 0; i < table.length;
i++) {
for (int j = 0; j < table.length;
j++)
table[i][j] = Terminal.lesInt(); // Terminal is a class that can read the terminal input
System.out.println("\t\t\t\tSum:");
// prints the values
for (int i = 0; i < table.length;
i++) {
for (int j = 0; j < table[i].length;
j++) {
System.out.print("\t" + table[i][j]);
System.out.println();
// sum of first column
int sumColumn = 0;
for (int i = 0; i < table.length;
i++) {
sumColumn += table[i][0];
System.out.print("\nSum:\t");
System.out.println(sumColumn);
Example of output:
1
2
3
4
5
6
Sum:
1 2 3
4 5 6
Sum: 5This is the output I'd like:
1
2
3
4
5
6
Sum:
1 2 3 6
4 5 6 15
Sum: 5 7 9One way of getting the sum for all the columns is to make a for-loop for each one of them, but there has to be a better way. I could apply the same hack to get the sum of the rows, but I still wouldn't know how to get the layout I want.After many hours of frustration I finally solved it (for-loops can be confusing, man) after I got a hint from a post in another forum: http://www.linuxquestions.org/questions/showthread.php?postid=624021#post624021
A more logical name to the integers actually helped a lot too. And here's the final product:
public class SumRowsColumns {
public static void main (String[] args) {
int[][] table = new int[2][3];
// gets the values
for (int row = 0; row < table.length;
row++) {
for (int col = 0; col < table[row].length;
col++)
table[row][col] = Terminal.lesInt(); // Terminal is a class that reads the terminal input
System.out.println("\t\t\t\tSum:");
// prints the values and sum of each row
for (int row = 0; row < table.length;
row++) {
for (int col = 0; col < table[row].length;
col++) {
System.out.print("\t" + table[row][col]);
int sum = 0;
for (int col = 0; col < table[0].length;
col++) {
sum += table[row][col];
System.out.println("\t" + sum);
System.out.print("\nSum:");
// sum of each column
for (int col = 0; col < table[0].length; // table[0].length is the length of row 0 (the number of columns)
col++) {
int sum = 0;
for (int row = 0; row < table.length; // table.length is the number of rows
row++) {
sum += table[row][col];
System.out.print("\t" + sum);
System.out.println();

How do I read text from specific rows and columns in a tree structure?
How do I read text from specific rows and columns in a tree structure? In a table you can specify the cell to read from but I have not been able to figure out how to do this with a tree structure.
You need to set two properties to activate the correct cell and then you can read it's string property.
The positioning properties are the "ActiveItemTag" and
"ActiveColNum" properties. With them you select the tree item by it's tag and the active column. The string can then be read from the "Cell String" property.

Keeping row and column headers while scrolling inside a Web Dynpro table
Hi,
I have to display a 2x2 matrix with storage location names on the x-axis (i.e. as Column Headers) and material names on the y-axis (i.e. row headers). The table data represents the quantities of a particular material in a particular storage location.
I am using dynamic UI generation to create this table. It can contain as many as 150 columns and almost as many rows. I dont want a page level scrollbar, and hence, have placed my table inside a scroll container UI element with a fixed height and width.
I need a way to let the users use the scrollbars inside the scroll container, but still let them see the row and column headers. Is there a way that I can do this in Dynpro for Java?

Can we hide the tables and columns from subject areas in the front end
Hi,
Is there any way to hide the tables and columns from the subject area in front end.I need to create a report with some tables which the user does not want to see.So after creating the reprot can I hide those tables and columns in the front endHi,
Your question is not that clear to me...do you want to hide the entire table/column that dont want to show up in the front end then you could do in Presneation Layer in the RPD by going Permissions in the property of that object.
But if you want to hide the column in the report that can be visible in the subject Area: go to column properties -> Column fomat...thereis Hide option.
Can you please elaborate your question...what exactly you are looking for...

Make Select rows and columns as read only in Table Control
Hi All,
I would like to know how to make certain cells in a Table Control as display only.
Table control should look like-(Those in bold are read only or in display mode)
<b>Name1 Idno1 </b> Address1
<b>Name2 Idno2</b> Address2
<b>Name3 Idno3 </b> Address3
<b>Name4 Idno4</b> Address4
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
(Blank row to enter name idno and address)
My table control should display all the above fields the way it is above of which first two colums and 4 rows should be read only,and the rest of the empty rows in the TC should be in change mode.i.e it must have provision to add new rows but not change the first two columns of existing rows.
In short I am looking at solution to hide particular no of rows and columns and <b>not the entire column.</b>In the PBO of the table control loop. just write these statements
NAME and IDNO considering the fields on the screen.
and WA_TAB is the table work area being passed to the table control to display the rows.
if not WA_TAB-NAME is initial and not WA_TAB-IDNO is initial.
loop at screen.
if screen-name = 'NAME' or
screen-name = 'IDNO'.
screen-input = <b>0</b>.
modify screen.
endif.
endloop.
endif.
which means that the fields are disabled only if NAME and IDNO are not initial.
