DataTable grouped columns - disable collapse

Hello,

We have a table with grouped columns, and the group header has a “closed: false” property.

We would like to disable closing the group (e.g. the user won’t be able to click on the header to close it)

What event should we catch?

Thanks!

In general, the only way to prevent hiding is to returnfalse fromonBeforeClumnHide for each column in the batch:

  on:{
    onBeforeColumnHide:function(id){           
      return this.getColumnConfig(id).batch !== "2009"
    }
  }

But I would like to suggest you remove grouping from this particular set of columns. Something like:
