How to have columns of TableView ocupy all of the parent

Question

How can we make the columns ocuppy all of the size of the parent? Why am i asking this? Because as we can see on a simple example the columns dont fill all of the size of table and this is ugly.

The only thing i dont want to happen to a column is to have it with less width than the contents of its column.

I want the solution to work for many columns.

How can we succesfully do it?

            }
            anchors.fill:parent
            TableViewColumn {
                role: "title"
                title: "Title"
                width: 100
            }
            TableViewColumn {
                role: "author"
                title: "Author"
                width: 200
            }
            model: libraryModel
            itemDelegate: Text
            {
              text: styleData.value
              elide: Text.ElideRight
            }
        }
    }
}

Has pointed on an answer something like

width: (table.width / table.columnCount) - 1

can be used but i dont want to happen in small widths for items/text to be cut i want the scroll bar to appear:

Answer 1

Like this ? -1 is just to avoid seeing an annoying scrollbar (probably caused by margins/borders)

TableView{
    id: table
    anchors.fill:parent

    style: TableViewStyle{
        handle: Rectangle {
            implicitWidth: 15
            implicitHeight: 15
            color:  "#000000"
        }
        minimumHandleLength: 30
    }

    TableViewColumn {
        role: "title"
        title: "Title"
        width: (table.width / table.columnCount) - 1
    }
    TableViewColumn {
        role: "author"
        title: "Author"
        width: (table.width / table.columnCount) - 1
    }
    model: libraryModel
    itemDelegate: Text
    {
      text: styleData.value
      elide: Text.ElideRight
    }
}
