Hi does anyone know how to stop users from moving a column in JTable whilst making the cells editable still?

does this help?


myJTable.getTableHeader().setReorderingAllowed(false);

It helped immensely.

One more question Flumpy, do you know how to clear the values of the table (cell values)?

use the TableModel?

TableModel myTM = myJTable.getTableModel();

for(int x = 0;x < myTM.getRowCount();x++)
for(int y = 0; y < myTM.getColumnCount();y++)
myTM.setValueAt(&quot;&quot;, x, y);


this example only works for a table of strings. same principle tho, as setValueAt(Object o, int row, int col) accepts any object.

hope that helps.

Yes it does, it was what I was doing originally. I was just wondering if I could completely remove the row. Thanks.

The JTable object uses a TableModel, often there is no need to use a table model other than the default, in whioh case the following will work.

TableModel tm = JTable.getModel();
if(tm instanceof DefaultTableModel) {
  ((DefaultTableModel)tm).removeRow(rowNumber)
}
else {
  // Hmmm, don't know how to remove row.
}

wont that actually remove the entire row, not just the contents tho?

Erm, yes, but isn't that what dellyjm wanted; &quot;I was just wondering if I could completely remove the row&quot;
