RowSorter.SortKey sortKey = new RowSorter.SortKey(columnIndexToSort,SortOrder.ASCENDING);
ArrayList alist = new ArrayList(1);
alist.add(sortKey);
((DefaultRowSorter)table.getRowSorter()).setSortable(columnIndexToSort , true);

Serial number column in Jtable

Apologies for this distraction.
I read at this forum about a year ago how to add a s/n column in Jtable such that all the nos are automatically updated/adjusted when a row is added/deleted. the count starts from the top down serially and unaffected by sorting.
pls help!

thanks a million BaltimoreJohn and especially camickr whose solutions to problems have been most helpful. applying the referenced post, i worked around the problem by resetting the values of the column having the serial number, based on table rowCount every time there is an operation on it(deleting, addition etc)

Makignone column in jtable NOT sortable

hi
i am using a TAbleSorter that sun provides to sort my table
JTable importsTable=new JTable();
MyTableModel model = new MyTableModel(handler.getImportableObjects());
MyTableSorter sorter = new MyTableSorter(model, 0);
sorter.setTableHeader(importsTable.getTableHeader());
importsTable.setModel(sorter);
MyTableModel is an AbstractTableModel that does soem custom stuff for me, nothign major.
MyTableSorter is a table sorter that overrides isCellEditable. i am doing this so that i can make the one column iwnat non-sortable not editable. it is however nto working. help?
thank you

Well.. u r using an abstractTableModel.. so the cells r anyways not editable.. U ve made all the columns except the first one editable by overriding the isCellEditable method.. It s not working?? There must be some other prob.. Post some more relevant part of the code wit tags

Disabling a single Column in JTable

I want to disable just one column on my JTable so that the user is not able to sort on that column. Has anyone done this?
Thanks,
S

It's difficult to give a definitive answer when you don't explain how you are sorting but most JTable sorting is done by detecting a mouse click and determining which column the click location corresponds to. Just add some logic to recognize you disabled column and bypass sorting code.

How to set different renderers to different cells in same column of JTable?

Hello Friends,
I need your help again...
Does any body knows, how to set different renderer's for different cells of same column in JTable..??
For ex.
Col1 Col2 Col3 Col4
A       A       A      A
A       A       A      B
A       A       A      C
A       A      A       D
Where A B C D would be different Renderers. I want set exactly same ,,, ie. one column with different renderer at different cell positions..
Right now i m setting renderer using statement bellow :
table.getColumnModel().getColumn(int).setCellRenderer(rederer_Instance);But with this, effect in the last renderer is applicable whole column....
Can any body help me out ?????????

Add and remove columns from JTable

Help me please!
A try to remove column from JTable. It's removed, but when I try to add column in table, then I get all old (removed early) columns + new column....
I completely confused with it.....
Here is my code for remove column:
class DelC implements ActionListener
          public void actionPerformed (ActionEvent e )
               int [] HowManyColDelete = table.getSelectedColumns();
               if (HowManyColDelete.length !=0)
                    TableColumnModel tableCModel = table.getColumnModel();
                    for (int i = HowManyColDelete.length-1; i>-1; i--)
                         table.getColumnModel().removeColumn (tableCModel.getColumn (HowManyColDelete [ i ]));
               else
                      JOptionPane.showMessageDialog(JOptionPane.getRootFrame(), "Column is not selected!");
     }

It's little ex for me, I just try understand clearly how it's work (table models i mean). Here is code. All action with tables take place through menu items.
My brain is boiled, I've try a lot of variants of code, but did't get right result :((
It's code represent problem, which I've describe above. If you'll try remove column and then add it again, it will be ma-a-a-any colunms...
I understand, that my code just hide columns, not delete from table model....
But now I have not any decision of my problem...
Thanks a lot for any help. :)

ALT+Up keys,but how to make drop down list appear.
Plz help,it's urgent.
Thanks in Advance

Hi,
In addition to setting DO_SUM = 'X' you need to specify function in H_FTYPE field. It should be set to 'AVG' in your case.
ls_fielcat-do_sum = 'X'.
ls_fieldcat-h_ftype = 'AVG.

A simple question about wrong sorting with multiple sort columns in Excel 2010

Hi, everyone! I have encountered a problem that I don't know how to explain.
So I post it here because I don't know if there is another more relevant forum...
I have a data sheet with the students' scores for the course.
All the data were generated with the randbetween function,
and pasted with the values.
To rank the students by their performance,
I did the sort with the column "total score" as the first sort-column
and "final term" as the second.
The weird thing to me is that the order of the data seems problematic.
That is, all the rows are sorted correctly with the first sort-column.
But for the rows with the same values of the first sort-column,
there are some rows whose values of the second sort-column are out of order.
(please look at the data file at
www_dot_kuaipan_dot_cn/file/id_67204268108546068_dot_htm
Please change the "_dot_" to the real literal dot.
Especially the rows with 56.7 as the first sort-column value
and some other values near the tail of the list.)
I tried to manually input and sort the same values of both columns
in a near-by region. The result was correct.
When some friend copied all the data to paste in Notepad,
and reload them in excel. The problem disappears.
Some friend also tried to wrap a round function at the values of the 1st sort-column,
the sorting order became correct!
But they could not explain why either.
How confusing! I even tried to swap the first and secod sort-column;
the output was right.
All the data were generated by randbetween function and pasted with values.
Where could all the special characters, if any, come?
Can anyone give me an explanation? I would be very grateful.
Thanks in advance!

Re: Sort is not in proper order
Sounds as if the data includes spaces or hidden characters that are affecting the sort.
That is indicated by the fact that manually entering the data resolves the problem.

How can I get (using API) the current sort column for some report

hello,
How can I get (using API) the current sort column for some report ? For example something like "fsp_sort_1_desc" - if the user sorts by the first column ?
I cannot use the :REQUEST for this, sometimes the current sort column is not in the :REQUEST, but it is still active.
I thought it was posssible by using
APEX_UTIL.GET_PREFERENCE (
p_preference IN VARCHAR2 DEFAULT NULL,
p_user IN VARCHAR2 DEFAULT V('USER'))
RETURN VARCHAR2;
function, but I don't really know which preference should I pass as parameter.
looking in WWV_FLOW_PREFERENCES$, i saw preferences_names like FSP4000_P527_R6281510839654570_SORT , I'm not sure how this name is formed.
I'm using generic columns for that complex report (which has a flexible number of columns shown), and the idea is that sometimes I have to overwrite that sort column, in case the user chose the version of the report with fewer columns than the previous one.
Can I get (using API) a list of all preferences set for some user ?
Thank you,

seems that it is FSP<app_number>P<pagenumber>R<regionnumber>_SORT.
is there anyplace where I can get these kind of things documented ?
Thank you.

Problem in specifing the intial sorting column of a report

hi
we have a report based on a table with 6 columns in our home page .we display all the six columns as sortable.
we also need to sort the contents of the report by 4th column by default when ever the user logs in ,but what happens is ,report gets sorted automatically depening upon the previous sorting column selected
is there any way of telling htmldb to sort the report by 4th column ..
many thanks
S.Jawahar

hi ,
this infotype has a interesting solution . In my case it was for US country .
We select the veteran status and this is field P0077-VETST which is stored in DB table .
Now based on this value and the molga of that pernr we need to look at the T5UVT table for the combinations avaliable for MOLGA AND VETST .
Based on the config's of this table the screen values are getting populated .
It dosent allow any combinations and the picked values are passed to the screen for fields Q0077-VETS1 VETS2 VETS3 VETS4 .
