Horizontal Scrolling + JTable + Java

I checked stackoverflow questions regarding getting horizontal scroll on JTable to work. Setting AUTO_RESIZE_OFF makes me a horizontal scrollbar, but at the same time, the table does not use the full width of the scrollbar.

I read a little, and it turned out that since 1998 this has been working bug (will Oracle fix this?)

I saw some tips on riding techniques, etc., but no one worked for me. And does anyone have an answer? It will be much appreciated. Basically, I need a table for automatically resizing, but allowing a horizontal scrollbar before compressing any of the column names.

Thank.

after talking with other answers - JXTable (in the SwingX project ) has an additional column layout property, which

  • fills the horizontal viewport (i.e. increases the width of the column) if their combined prefix is ​​less than the current width, given autoResizeMode
  • saves the size of the columns in their pref and shows the horizontal scroll bar if their combined prefix is ​​greater than the current width

There's a bit of internal tweaking, so (biased) would suggest using JXTable. Or look at its code and c & p - everything is allowed, everything is open source :-)
