I have two JTables
one in main viewport and one in footer viewport, using JideScrollPane
.
the problem is when the main JTable
's view is customized, the footer JTable
remains the
same, is there any way to synchronize their view?
thanks.
EDIT: Here's a demo that will synch up the resizing of two tables that have similar columns. The idea is:
TableColumnModelListener
for each table's column model.columnMoved(...)
[left as an exercise]This shows two-way synching:
