The width was decent, except that on small paper (A6) it was
wider than the paper size.

The height was terrible - the minimum size possible. It was too small
for even a single line of text. That made it hard to grab the table edge
(instead grabbing a row edge) when trying to resize.

Now the height and width are limited to the page/view size,
and based on the number of rows created.  One possible enhancement
would be to use the border width instead of the page width.
