I'm using JTable with option:

_table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

Table is added to JScrollPane.

I wan't to set table columns width every time when table is resized. In
doLayout-method I put the new width for column by using
setPreferredWidth-method. 

_table.getColumnModel().getColumn(0).setPreferredWidth(width);

Problem: 

Which is the right method to find out JTables visible width and does
this method work with or without JScrollPane's horizontal and vertical
scrollbars?

Thanks in advance,
