Table chart conditional formatting based on datetime columns and multi-column conditions

[plaes]

Here are few things that I currently miss from table chart:

1. Date/datetime column support for conditional filtering
2. Conditional filtering based on multiple columns (ie. if required_date < NOW() + interval 14 days && status == Unordered`).
3. Ability to group columns (colspan support)

Also, UI for colouring "entire row" could be somewhat more intuitive (there's lot of confusion in #22790). PR in #43692
Ideally there should be a separate checkbox for "entire row", instead of hiding this in the column dropdown together with column names.
