I run under NT4/SP4, JDK1.2.1.

I create a JTable, the I add columns. When I add a column, I
initialize its identifier and Size (and min/max/pref. size).
The pb is that when I add the third column (for instance), using
"table.getModel().addColumn(name)" - model is DefaultTableModel -,
that re-initialize the different size of all the previous columns
to their initial size (75).
If I do directly "table.addColumn(new TableColumn(int));", the pb
does not appear.

The following code show that, at display, all the columns have
a size of 75, except the last one.

***************** end of code *******************

I may miss something, but I guess it must be a bug. I could'nt
find something like this in the existing bugs.

Keep enjoy Java!
