Colspan performance

See snippet. I have a datatable with 10k items and a few colspans. With colspans the performance when scrolling degrades enormously. Disabling the colspans makes it run super smooth.

Anything I can do to improve this?


  • It also looks like the entire table is getting refreshed when spans: true is used whenever anything updates.

    I'm trying to change a cell when I clicked on it (toggle) but this triggers the template function for every row and that freezes the application.
