JTable cell span merge

Question

Hi I\'m having a problem with Java JTable. I want to merge or span cells. I did it using this examples:

The same example is available here. It seems the problem might be in MultiSpanCellTable getCellRect() implementation. Column margin is contributing to the cell width and generating this offset. Looks like the problem goes away if you replace:

cellFrame.width = aColumn.getWidth() + columnMargin;

with:

cellFrame.width = aColumn.getWidth();
