Moving columns in JTable

hi all
i'm having a slight problem after i've moved a column within my JTable, i need to reallocate the column index numbers. i'm using a sorter for the data, so when i move a column and select another column (or that one) it sorts a different column to the one selected based on the original (pre-move) indexes ( i do hope that makes some sense).
i have a mouseDragged listener which works fine when moving a column, i just now need to add the index changes for all columns to it but i keep coming up with very very bad code that doesn't work.
any suggestions would be most appreciated.
thanks heaps...
Takis

i've actually been fiddling with those and that is actually where my problem lies.
i use the following:
int viewColumn = columnModel.getColumnIndexAtX(e.getX());
int column = tableView.convertColumnIndexToModel(viewColumn);
the sorter then works on "column".
problem is, that when the column is moved, the viewColumn changes, but the column value remains the same. i've also tried sorting on the view column but then it gets even more confused.
i just can't seem to figure it out...

Moving Columns in Jtable. Columns not in sync with header

Hi,
I got several tables within a scrollPane. So I use the add method on the scrollPane to add them. In order to see the headers I add the header separately :
add(table.getTableHeader());
add(table);
The problem is the following :
When I am moving my Column around, the header moves around, however the columns don't move ! So The header does not correspond anymore to my column !
Do someone have some ideas how to get ride of that problem ?
Thanks
Emmanuel

One thought: Add the tables to another container, such as a JPanel and then add the panel to the JScrollPane

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. :)

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.

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)
