How to group by an object cell about ka-table

[aleksei-baryshnikov]

I mapped, but would be great to have a cb in the colDef.
Mb will do it by myself when have time.

hi @aleksei-baryshnikov you can have [object].[prop] keys (in your example it is 'type.value') in that case grouping will work

But in some cases it could be { value: { key: value } }.
In that case should I specify that for each column?
Is it possible to have a function in colDef to build the groupKey?

Can't you just map your data to type.value structure ?

[aleksei-baryshnikov]

I can't because in some cases I need to aplly special formatting for the cells. Saying that a cell value couldn't be a string. This is why it would be nice having a property like format.

For me the problem is that the cell contains some meta information which needs for making some actions when an user clicks on a cell. And ka-table takes it as is, as you can see on the screen. Here is no possibility to define key for cell rendering and key for cell grouping separately.

If I set key: cell.value then I am missing cell.actions in the table config, like FormatFunc.

you can map data and add separate prop for grouping, and by onClick or any other actions you can access original data though rowData, example: https://stackblitz.com/edit/table-grouping-ts-hdf9h3?file=Demo.tsx

That works but how to be with groups? I want to have the same formatting in there.
But in grouping I don't have rowData if a group is collapsed, so it doesn't give me actions.

There is groupItems in Group, you can access required data using it, demo: https://stackblitz.com/edit/table-grouping-ts-wg5rpj?file=Demo.tsx
