qml 5.12 TableView columnt width depending on content?

[SergeyK12]

Hi!
I'm wondering, is there any way to adopt width of the columnt to the content?
I got so far, that

TableView {
            id: table
            Layout.alignment: Qt.AlignCenter
            Layout.preferredWidth : 800
            Layout.preferredHeight: 300
            columnWidthProvider: function (column) { return 100 }
            rowHeightProvider  : function (row)    { return 100 }
            clip: true
            model: StandardModel {}

            delegate: Rectangle {
                border.color: "blue"
                border.width: 1
                color: (heading==true) ? "red" : "green"
                Text {
                    id: text
                    text: tabledata
                    font.pointSize: 12
                    anchors.centerIn: parent
                }                
            }

Suppose, that i could calc width of the Text (there is a function named contentWidth ). Should i try to iterate over rows in columnWidthProvider to calc the maximum value of the cells in the column and returnin this? (i dont get how to iterate over rows in column)

Here is an example of my table (but its obvious that columns should be different width which known only runtime)
