Empty values in number type columns are parsed as empty strings instead of null

[develleoper]

When I'm parsing a column I have specified as numerical using the colParser parameter, it is returning empty values as empty strings, instead of nulls.

This results in JSON with an incorrect data type down the line; is there a solution to this?

Seconding this. If parsing as an empty string is desired, then the cell data could have been "", which also results in parsing as empty string.
