            movable: false
            delegate: aldJira
            width: 100
        }

        // more columns

        rowDelegate: Rectangle {
            height: 30
            color: styleData.selected ? "skyblue" : (styleData.row % 2 == 0 ? "whitesmoke" : "white")

                }

                Component.onCompleted: {
                    console.log("tHeader.onCompleted", tHeader.width, width, styleData.column, styleData.value);
                    if ((styleData.column === 10) || (styleData.column === 9) || (styleData.column === 8)) {
                        cbHeader.visible = true;
                        tHeader.visible = false;
                    } else {
