headerRenderer will execute multiple times when the columns has frozen: 'left' and frozen: 'right' about react-base-table HOT 3 CLOSED

That's a good question, as internally there are 3 tables to implement the column frozen feature, so it would be called 3 times, not sure what kind of feature you want to implement, but I'd say it's easy to determine which table is calling it and it's intended not passing it to the callback, maybe I would add it if it's really needed, I just don't want to bloat the API, for example you could just check the first column from columns if it's frozen and which direction it is, and you will know which table is calling the renderer

In my practice, I always take those tables as the same, and don't care about which table is calling the renderer, I guess you want implement something like column groups? I could share with a screenshot of the advanced table component we are using internally which is built on BaseTable with much more features, including grouping, selection, columns settings, columns reordering and column groups

from react-base-table.

I'm not sure if the column grouping feature should be builtin the BaseTable, as it's a userland feature IMO, but I will provide some snippets first

from react-base-table.

I am understood what you said, thank you very much
