Filtering out the blanks in the column

In the column of data table, I have multi Combo filter working by filtering the present year value but I need to filter with the blank/null/empty value as we can see in the Microsoft Excel. How to implement the same in webix.

Please help me on this

Thanks in advance,

Hi,

It is possible only with a custom compare method: https://webix.com/snippet/1170cf0c
