Indeed, and this commit pops `org-table-last-alignment' if the first
column has been removed by `org-table-clean-before-export'.  The same
problem must have caused a one-off error when setting the alignment in
LaTeX tables, bu it seems nobody has noticed this so far.  Anyway,
also this is fixed now.
