This could be useful for organizing multiple columns in your table if you want to merge everything back into a single table. Column groups can be expanded and collapsed, and can help when using the column search.
Your only option right now is to build your own search functionally.
Essentially you would need a text entry component that fills a user specific column. Then you use a single value column to bring that search value into all tables. Then an IF column, or series of IF columns would be used to compare your single value column to all columns you want to search. The IF column could be set up to return ‘true’ when there is a match. Finally filter your collections where the IF is true.
It’s a decent alternative, but will eat into your update count as you are updating the user specific column in real time as you type.
