Hey @KES777

Interesting use of the header filter there.

I had never really intended the header filters to be used to filter anything other than their current column which is why they were tied to a field name.

But i can see why this may be a useful option in certain circumstances.

The issue it presents itself that there is no meaningful way to send this data back when using ajax filtering.

I would suggest that you make up a field name for your column that isnt represented in your data, that way you can use the header filter.

I hope that helps

Cheers

My use case is next: I do not want to show row's id (because usually it is just a noise), but I want to find rows by ID. For example by IDs from log files.

Currently I use formatter which returns just empty string =)

Also another interesting usecase is when I get from server range data type: [ '2019-01-02', '2019-02-07' )
This one field I display as two columns: From and Till. To filter and edit such columns a bit complex, but possible.

Thanks

Hey @KES777

In your second usage case i would recommend using a mutator to generate a new field that contains the merged data, then using a filter function that checks the values in the two fields seperatly.
