Removing Tabulators from all coloumns in a table

Hey,

I need a little help. I have a table there are integer, date, string coloumns in it. Almost every column has one or more cells with just a tabulator. How can I change those tabulators in the table with empty cell or missing value?

I’ve tried String manipulation(multi column) but it doesnt work on date and integer coloumns.
