n#779627: fixed writerfilter import of grid when there are nested tables

When a nested table is ended, it resets the m_nCell to 0... and thus the
filter forgets about the previous cells of the outer table row it is
importing. Using a vector to store the m_nCell values for each table
solves the problem
