Subject: [PATCH] [uicomponents] omit table separators that double the
 container border

The last column's right separator and the last row's bottom separator sat on
top of the table's 1px container border, giving those edges a doubled, thicker
look. Hide them when the content fills that dimension (so the edge coincides
with the border); keep them otherwise, so a table with empty space below/right
still delimits its last row/column.
