Tough question, as far as I can tell...

I need to set the visibility of many columns in a JdbTable to
column.setVisible(TriStateProperty.FALSE)

This method takes a tremendous amount of time.
column.setHidden(true) is very fast, but it doesn't really affect the grid.

Other than jdbTable1.setHiddenColumns(new int[1,2,3])...

Is there a faster way to hide specific columns? Is this a Java glitch?

Easiest way is o do this from your DataSet, not in the jdbTable, since you
are first loading the TableModel BEFORE, you affect changes on the
JdbTable's TableModel and CellEditors/Listeners.

I AM doing it in the DataSet.
DataSet.getColumn(n).setVisible(TriStateProperty.FALSE).
