If I understand Your problem correctly then Your JTable size is too large.
The inital sizing of JTable is something strange.
You can try out the following:
TableColumnModel columnModel = table.getColumnModel();
columnModel.getColumn(0).setPreferredSize(20);
columnModel.getColumn(1).setPreferredSize(20);
Dimension preferredViewportSize = new Dimension(20 + 20, 50);
table.setPreferredScrollableViewportSize( preferredViewportSize);
You should then receive a table of size 40 x 50 pixels, if Your table
component is contained
in a scrollpane.

Subject: Re: Help with JTable column width
No, that doesn't help but thanks for the suggestion. I have found a
partial solution, but I don't know why my original method fails.
When I would change the host status I need to update the icon in
column 0. To do so I used the following code.
public void statusChanged(RemoteHost host)
{
tableModel.fireTableRowsUpdated(hosts.indexOf(host),
hosts.indexOf(host));
}
The call to fireTableRowsUpdated() is what messes up the column
widths. If I change this to a simple repaint() on the JTable the new
status is correctly displayed. Of course, listeners are not
notified, but I can handle that in other ways.
Isn't it the case that I should call fireTableRowsUpdated() when I
know the TableModel has new data to display?
