Prevent Adding Rows To Editable DataTable

Hi,

I am trying to create a DataTable with fixed number of rows and columns but editable data. I was successful in creating the table as expected.

But on later testing I found that when I copied more than one row from the table and pasted it at the end of the table (i.e pasted on the last row), it resulted in additional rows.

Is there any way to stop this from happening? i.e prevent addition of new rows in an editable DataTable.
