Blank(null) cells within Datatable

I'm using a datatable within a TEST, that has several rows and columns.
There is however one column that has numbers to input; but I intentionally left the last 5 rows of that column BLANK (NULL).

When I attempt to run it, it errors out when it hits that empty field.

What can I put in that field to represent a 'BLANK'?

Hi cocojava,

Can you try putting a single quote (') in those last 5 rows? When you put a single quote in a cell and hit enter, you can see the cell still blank. That being said, you actually put a single quote but still the cell is blank.

Hope it will solve your purpose.
