How can I add TableModelColumn dynamic

Doberman_ww

My Qt version is 6.4.1 and use QtQuick 2

A TableModel should be like this。

    TableModel{
        id:tableModel
        TableModelColumn { display: "checked" }
        TableModelColumn { display: "checked2" }
        TableModelColumn { display: "id" }
        TableModelColumn { display: "time" }
    }

but how can i add other TableModelColumn with js.

I have tried createObject and push in tableModel.columns.like this.

    Component{
        id:tableColumn
        TableModelColumn{
        }
    }

functioin addColumn(){
        var col = tableColumn.createObject(table.tableModel,{"display":"key"})
        tableModel.columns.push(col)
}

Unfortunatly, the tableModel.columns has been changed,but tableModel.columnCount didn't. Only columns changed, and it didn't work on the TableView.

Maybe I need a method like TableView.addColumn in QtQuick 1.
