headerRenderer will execute multiple times when the columns has frozen: 'left' and frozen: 'right'

[dingchaoyan1983]

As the title mentioned, when I have a table and the columns not only contains the left frozen columns, but also the right frozen columns, because I want to merge some columns in header, like this example https://autodesk.github.io/react-base-table/examples/multi-header, so I need implement the callback headerRenderer, but this callback will be called 3 times, and there is no indicator which is left table main table, and right table, in user's (developer who use this component) view, I think this function will be called one time only, because there is only one header.

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

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
