The remaining logical height is wrongly added to the last row of a table, not spread on the rows.

Cells heights are not proper when rowspan cell have its own height and rowspan height is more than the height of the rows present in rowspan.

After calculating logical height of the rows in the table, we are recalculating the height of the rows present in rowspan. Based on the ratio of row's logical height, we are distributing rowspan cell height in rows.
In this patch, We are applying this approach to only first rowSpan cell in the table. Other rowSpan cells in the table are uneffected by this approach.
