Red         1
Green      2
Blue         3

Hi...
You can use "Add Index Column" function in Add column tab as below :

How to create a column with increasing numbers in h:dataTable?

I need to make a table that would have a column with order numbers, starting from 1 and increasing by 1 for every row. I tried using JSTL for this but it seems it is being ignored (as it probably should). My code is below. I know I am supposed to use getRowIndex() with bound tables, by my table isn't bound to anything...
I could hold the number in the backing bean but that seems like a total overkill.
Is there a proper way to this in JSF? Could I maybe somehow reference this (meaning tha table itself) within the EL expression?
<c:set var="month" value="0" />
<h:dataTable value="#{loansManager.rates}" var="rate">
            <c:set var="month" value="${month+1}" />
     <h:column>
          <f:facet name="header">
               <h:outputText value="Month" />
          </f:facet>
          <c:out value="${month}" />
     </h:column>
     <h:column>
          <f:facet name="header">
               <h:outputText value="Rate" />
          </f:facet>
          <h:outputText value="#{rate}" />
     </h:column>
</h:dataTable>

Bind the datatable to the backing bean and use HtmlDataTable#getRowIndex().
You can find here an example: [http://balusc.blogspot.com/2006/06/using-datatables.html#AddRowNumbers].

Add column with row number to table

Hi,
to a table view I'd like to add a new column that contains the row number for each row.
I have many data sources (twelve) and with the union operator I create one output dataset. The output data is sorted by the arrangement of the input ports of the union operator.
Is there a way to add a column with its corresponding entry number?
Regards, FT

I have a similar question to the original post. It seems your answer will fill the new field in all rows with the same value. But, what if we want an actual row number?
I am simply looking to add a row number to a table. I only have one data source. The business scenario is that the output of the data service is sorted in descending order on value. I want to be able to select the first 10 (i.e. the top 10 items based on that value).
Even if I can solve my business scenario without using a row number field after the sort, it seems like a technique that would come in handy.
Any ideas? I'm pretty new to using Visual Composer so I may be missing something obvious.

How do I print column letters/row numbers in Numbers?

In '08 someone asked about printing row numbers and column letters in a Numbers SS. The answer: take a snapshot (CMD-SFT-4) or use Excel.
I am using iWork09; the problem continues with it. Has this flaw been fixed in later versions of iWorks? When I print the spreadsheet and a formula sheet, the formula sheet is pretty worthless if the spreadsheet has no colum/row identifiers. So much for having someone else audit my formula work.

Supply the auditor with a copy of the file, rather than a printed copy of the document. If she needs a printed copy of the formula list, that's easy to obtain from the file. When she clicks on a cell containing a formula, Numbers colour-codes the cell references and highlights the referenced cells with those colours.
Use Header Row and Header column cells to label each column and row. Set Numbers preferences to use these labels in the formulas to name the referenced cells.
Add a column to the left of the table to contain row numbers, and a row to the top to contain column letters. The row numbers are easy to generate with a simple formula; the column letters require a little more thought, especially for those past column 26 (Z, followed by AA), but it's doable.
Use the suggestion (auxiliary tables) suggested above by Wayne.
Two other suggestions:
First, if this feature is, in your estimation, a significant flaw in Numbers, send feedback to Apple requesting it be included in a future version of numbers. Use the Provide Numbers Feedback item in the Numbers menu, or the link in this message—both go to the same place.
Second, Use the application that best meets your needs, whichever application that turns out to be.

TangellaHow do you define "the beginning rows in the table"? Rows in a relational, heap table have no "order" to them. There is no concept of "first".
And once that is defined, why would you want to assign sequence number to only 10k our of "millions" of rows?

Using forms to fill columns not rows

Can I use a form to fill columns instead of rows? I have students names in a header column (each student is a different row) and I have assignments in different columns. Can I use a form and have the column info appear at the top with a list of students in the form to fill in grades for that assignment. The way it is now, it shows a single student at the top of the forum and all the assignments in the fill form. I want the opposite. I really don't want to create a column with a different student in each one. Too long of a table.

I did that for 2 hours last night and found out the sort doesn't work on the table with the references, so that meant on the form, nothing was sorted right (I have four fields I have to sort by depending on what I am doing). I tried creating a master table that I could sort, but the data table that the forms feed into won't sort. I ended up realizing that even though you can reference the cell of another sheet or table, it won't sort when the referred to table is sorted.
Example:
Master table
Bob (in cell A1)
John (in cell A2)
Adam (in cell A3)
Data Table
Bob (referrenced =A1)
John (referrenced =A2)
Adam (referrenced =A3)
Sort the Master Table:
Adam (in A1)
Bob (in A2)
John (in A3)
The data table does this:
Bob (referrenced =A2)
John (referrenced =A3)
Adam (referrenced =A1)
You can see the data table maintains it's original sort order regardless of how the master table is sorted.

Populate columns with row values in Sql Server Reporting Services

I have got a dataset with 2 columns named Row and Title. There are 8 rows in this dataset and I want to display those 8 titles within columns in a table. So I create a table with 8 columns and set each column's expression to
=LookUp(Fields!Row.Value,1,Fields!Title.Value,"Titles")
=LookUp(Fields!Row.Value,2,Fields!Title.Value,"Titles")
=LookUp(Fields!Row.Value,3,Fields!Title.Value,"Titles")
However only the first column displays a title. The other 7 display nothing. Is my expression wrong?

Hi,
Is the row datatype non-numeric? Maybe the lookup is failing for that reason. You coulr try adding a conversion to the field:
=LookUp(cint(Fields!Row.Value),1,Fields!Title.Value,"Titles")
Could you, perhaps, instead use a tablix table and put the Title column on the row group? That would pivot the data the way that you want it.

Column with consecutive numbers in Numbers '09

Very simple question -- I did a search for this, but because my query involves the word "Numbers," it returned everything!
Okay, I have a list of 500 rows. I want to add a very simple column in Column A, that simply has "1" in Row 1, "2" in Row 2, all the way down to "500" in Row 500. If I type "1" into the first column, I can't seem to drag the cell down and do that -- it just inserts "1" into the entire column, which isn't what I want.
In other words, I want Column A to very simply look like this:
1
2
3
4
5
6
7
8
etc.
What's the right way to do that? Thanks.

It probably is in the Numbers '09 User Guide, but if you don't know the answer, and haven't developed some good search techniques, it's one you might have trouble finding in the Guide.
John's subject line suggests he'd search using "consecutive" (zero occurrences), "number" (vast number of occurrences) or both words together (zero occurrences due to the absence of "consecutive").
"pattern" works, but I found that out by scanning Chapter 4, finding the paragraph that dealt with this, then using what appeared to be a potent word for a search. "You can also add values to cells based on value patterns" is the first line of a paragraph on page 76 (not 78, which deals with conditional formatting) of the English language edition of the guide.
I for one appreciate that John did a search, whether of the Guide or of this forum, before posting his question. That his search was unsuccessful is not really surprising; the information is moderately well hidden.

Barry

APEX Report - how can i create column with serial numbers in a report

Need help
I have created a report with displaying no of rows resticted to 43, every time i genarate this report i would like to add serial numbers from 6 to 48
apear in additional column. How can i do this?

This is not really an APEX question, and would have been better posted on the {forum:id=75} forum.
Note also that the best way to get fast, effective answer to questions is to provide sufficient information for people to fully understand them:

You should also ensure that your forum profile is updated with a better handle than "user8308442".
Getting back to the question, one way to do this is using the analytic function ROW_NUMBER():

select
          5 + row_number() over (order by query_data) sn -- use required ordering here
        , t.query_data

Is there any easy way to show row numbers in JTable?

Just like in Excel.

I think the easiest way would be to make your first column the row numbers, then make your own cell renderer for the first column that renders the text in like, a JLabel with a gray background and a raised bevel border or something. You could even go sofar as to write a new selection model that selects an entire row when you select a cell in the first column. Getting the row number is easy enough, as the row and column number are both passed to the getValueAt() method of the table data model.

Pre populate field with integer numbers?

Hi,
I want to pre-populate my field which is integer type with numbers in a sequantial order like 101,102,103,104...
How can i do this with 10gr2?
Regards.

Actually i have two tables.
First table has ID1, NAME1, REF1 columns.
Second table has ID2, NAME2, REF2 columns.
ID1 and ID2 is autonumbered id columns. NAME and REF columns are emtpy columns. I populated NAME1 and NAME2 manually entering data from my project.
Now i want to relate each table's rows one by one, i.e., one to one cardinality. Therefore, i have to populate first table's REF1 column with sequantial numbers, and then manually enter corresponding number to table two's REF2 columns.
I don't want to use ID columns, because i insert data these tables at different time intervals.
Hence, when i query TABLE1's NAME1 data, i will see corresponding data in TABLE2's NAME2 column via this relationship.

Merging two columns with muliple rows in Numbers '09

I am trying to merge two columns each with 100 rows and related data. Column one is the street address and column two have office numbers. The final result would be one column with 100 rows with address and office numbers.

Ed Carreon
Hi Ed,
Use the CONCATENATE() function.
Street address in column D, Office number in Column E
100 Smith ST 212
Formula: =CONCATENATE(E," ",D)
Result:
212 100 Smith ST
Note the formula has three arguments, the reference to column E, a text literal (" ") containing a single space, and a reference to column D.

Tables with differing numbers of columns in subsequent rows

I'm trying to create a table that has say 3 columns in row one, 2 columns in row two, 5 columns in row 5. I've done it so far by merging cells and splitting them and then asking it to distribute columns evenly but the columns are not distributed evenly.
The column width button is greyed out so I can't set the width manually and so my table looks really unprofessional.
Is there a better way of creating such a table and getting equally distributed columns?
Many thanks
sekentious

an example of merging cells is here
[http://www.crionics.com/products/opensource/faq/swing_ex/JTableExamples4.html]
scroll down to 'Multi-Span Cell'
run the program, highlight some cells, click combine.
if that's the type of thing you're after, modify your code per what's in 'combine'
note: the original code (now) produces a stack overflow error (don't know if it's been fixed in the above link),
but if you get that error, in AttributiveCellTableModel's setDataVector( Vector newData, Vector columnNames )
change
setColumnIdentifiers(columnNames);
to
columnIdentifiers = columnNames;

Print Row Numbers and Column Letters

How do you tell Numbers to print the Row numbers and Column letters? This was very simple in Appleworks (print dialog box had that option). Can't find it in Numbers though.

Here is a script doing all the job for us.
Just select one or several cells in a table and run the script.
It duplicates it, add an header row, an header column, insert the needed labels and fill the other cells with a formula grabbing the contents of the original table.
--[SCRIPT build a table with headers]
Enregistrer len tant que Script: build a table with headers.scpt
déplacer le fichier créé dans le dossier
<VolumeDeDémarrage>:Users:<votreCompte>:Library:Scripts:Applications:Numbers:
Il vous faudra peut-être créer le dossier Numbers et peut-être même le dossier Applications.
Selectionner une cellule dans la table à dupliquer
menu Scripts > Numbers > build a table with headers
Le script duplique la table et crée des en-têtes de lignes et colonnes.
--=====
L'aide du Finder explique:
L'Utilitaire AppleScript permet d'activer le Menu des scripts :
Ouvrez l'Utilitaire AppleScript situé dans le dossier Applications/AppleScript.
Cochez la case "Afficher le menu des scripts dans la barre de menus".
+++++++
Save the script as Script: build a table with headers.scpt
Move the newly created file into the folder:
<startup Volume>:Users:<yourAccount>:Library:Scripts:Applications:Numbers:
Maybe you would have to create the folder Numbers and even the folder Applications by yourself.
Select a range of cells in the table to 'duplicate'
menu Scripts > Numbers > build a table with headers
The script duplicate the table and inserts columns/rows headers.
--=====
The Finder's Help explains:
To make the Script menu appear:
Open the AppleScript utility located in Applications/AppleScript.
Select the "Show Script Menu in menu bar" checkbox.

Fill a column with serial number

Hello, all seniors..!
my table has one empty tno (number) column, that i now wish to fill it with a series of numbers
for as many records that are present.
the sample table data is; 1 SELECT TXN_DATE
2 FROM PTXN
3* WHERE ROWNUM <10
TXN_DATE
18/03/2010
02/02/2010
10/02/2010
05/04/2010
15/05/2010
25/01/2010
03/02/2010
15/01/2010
25/04/2010
9 rows selected.
I issue this command;
update ptxn
set tno = rownum
With the above Update SQL, the TNO column got filled with the exact number of records. Like this,
SELECT TXN_DATE,tno
FROM PTXN;
TXN_DATE         TNO
03/02/2010          1
15/01/2010          2
02/02/2010          4
25/04/2010          8
25/01/2010          3
18/03/2010          6
15/05/2010          9
10/02/2010          5
05/04/2010          7
9 rows selected.
what i actually want is to sort my table (ptxn) by column 'txn_date' wise and then fill series.
Like this;
TXN_DATE TNO
15/01/2010     1
25/01/2010     2
02/02/2010     4
03/02/2010     8
10/02/2010     3
18/03/2010     6
05/04/2010     9
25/04/2010     5
15/05/2010     7
How do i modify my Update statement ot any other solution, please suggest.
