Resolves the bug fdo#59117 missing borders of last column

  When writingmode is set to RTL, the table is start drawn from Last column
to first column.  There is no problem with left&right lines, Because these
are not depends on the LTR or RTL writingmode.  But the bottom & top line
depends on writing mode.  As these two lines are drawn from previous cell to
next cell(left to right) the nX value should be nX-1 in RTL writingmode.
