Index.html.heex, create button and filter the content if value is in cell

In my table are a lot of columns. Now I need a possibility to filter if a cell have value or not. It would be nice if there is a button.
If I press the button, all lines of the table which are have a empty cell are not visible.

Is that possible? And how can I start?

Yes it is possible.

I would suggest You start by your contexts queries to list your resources and add the possibility to filter, limit, offset, order here

In fact, You should be able to test in the console

Then in the UI it will just be a matter of managing and passing the right parameters to the queries
