I'm finding that I cannot remove a table's right vertical border even when setting line color to nothing, and 0 border width.

I inserted a table (from Lists & Pickers section of UI Elements) directly onto a screenpart canvas.  It is not placed inside a container or anything.

In other words, there are no screen elements above or below the table in the Z-Order.

You can see in the properties for the screenpart that I've set the thickness to 0 and line color to nothing.

I also set everything I could for the table itself to be no line.

But when running the screenpart, notice that it removed the left and center vertical lines, but you can see that the rightmost line is still there.

Any idea how I can remove that?
