When a row is highlighted in the tables, a vertical white line appears between cells.
It's only in debugger, because it set's vertical
lines to be invisible.
This is bug in JTable. If you try simple example with JTable
and use setShowVerticalLines( false ), white lines will
appear in selectin row.
Here's how I did this in the IFDEF debugger:
// No white clipping lines on selected table rows: reduce separator
// to 0. That means text may touch but HIE prefers this.
table.setIntercellSpacing(new Dimension(0, table.getRowMargin()));
Resolved for 3.3.x or earlier, no new info since then -> closing.
