How to turn off the filter for a table column again

Hi,

I have a table for which some columns should be filtered. I have added the filter now for just one column.

When I'm typing something in the filter field, the table gets filtered. But how can I turn off the filter again?

The column field is type numc4, so when I just delete the filter field, it contains '0000', and the table is

getting filtered by that value.

So can anybode tell me how to turn it off?

Thank you!
