Issue #470 resulted in TableCell.SetClickedFunc() being added

This allows you to provide a callback fn, when a cell is clicked (even if it is unselectable)

The issue is, the callback provides no way to identify which cell was clicked (and it cannot be retrieved from Table.GetSelection() if the cell is unselectable. Also I suspect this event is triggered before the selection would be updated anyway).

This makes it very difficult to attach a generic click handler to all your header cells - for example if you wanted to install the same callback for all your header cells, then use TableCell.GetReference() to decide how to sort the table

Not sure if I'm missing something, but is there a way to identify the cell which was clicked?

Could the tableCell be passed as a parameter to the callback fn?

Good catch, thanks!

Just updating your example, since width is now returned, and callback must return a bool..

func getCallBackFor(tc *tview.TableCell)(func () bool){
    return func() bool{
        // i have handle to the tablecell now
        tc.ScratchNuts()
        row,col,width := tc.GetLastPosition()
        return false
    }
}
