JFace's TreeViewer - Strange alignment on first column

I use a TreeViewer. I do not understand why the first column of my table has an empty space on the left. This does not depend on the column, because if I change the first column, the gap is still there. The second column is well left-aligned.

Solution

  • This is space left for the tree expand / collapse twistie image. The space is always reserved even if you have no children for the tree nodes.

    If you don't have any children then use TableViewer.
