1. create a table with 3 rows, 3 columns.
2. merge the first two cells in the first row.
3. veritical split the last cell(the cell after the merged cell) in the first row. 
The table structure becomes messy after the third step.

The bug is in ""tabletools/plugin.js"", cellInRow function. Developer should avoid adding duplicate cells, similar with ""cellInCol"".
