Set a column width of JTable according to the text in a header

Question

I need to get an appropriate table size according to a text in a header. It contains abbreviations of czech names of days like: \"Po\", \"Út\", \"St\", atc. but instead of t

Answer 1

I came to solution :-)

I had to change the look and feel before I calculated appropriate column widths. When I did it the other way around, the calculation was out of date.

So I only needed to set the correct widths like this:

table.getColumnModel().getColumn(col).setPreferredWidth(width);

And then change the size of the viewPort like this, because the table's prefered size is now correct.

table.setPreferredScrollableViewportSize(table.getPreferredSize());

Thanks! ;)
