resize columns in JTable

[Daniel Luis dos Santos]

Hello,

I have a JTable on which I set a model derived from AbstractTableModel.
I then want to put a fixed size on the first column.
When I get the column model from the table or from the tableheader it is empty.

How do I synchronize the column model to the table model ?
How do I set the size attributes of a table column ?

TableHeader? I think you want the TableColumnModel returned by
getColumnModel(), as shown here:

If that's not it, you might try posting an <http://sscce.org/>.

Have a look at the code for Vercheck. I put lower and upper bounds on
each column that the user can adjust within.

You are right. Lazy me. Thats probably the first step in solving the problem.
