Sorting groups when grouping is active

[RaskaTheFurry]

Hello,

I use the table with static mode off and I assume, that this means, that I have to do the data sorting myself. When im not using grouping in this table, the data is sorted correctly how I want it. But when i turn on grouping, the groups arent sorted how the data is sorted. It seems that numbers are sorted first, then null value and then strings? I would like to have null values first, above the numbers, if it is indeed being sorted like that. Or give us a way to sort it ourselves maybe?

As an example, lets say the groups are [null,"1", "2", "a", "b"] ( thats how the data is also sorted and how I want the groups to be sorted ). The way it works now the groups will be sorted like this: ["1","2",null,"a",b"].

My suggestion is to add group sort property, that would accept a sorting function.
