\qmltype TableView
\inqmlmodule QtQuick.Controls
\since 5.1
\ingroup views
\brief Provides a list view with scroll bars, styling and header sections.
\image tableview.png
A TableView is similar to \l ListView, and adds scroll bars, selection, and
resizable header sections. As with \l ListView, data for each row is provided through a \l model:
\code
ListModel {
id: libraryModel
ListElement {
title: "A Masterpiece"
author: "Gabriel"
}
ListElement {
title: "Brilliance"
author: "Jens"
}
ListElement {
title: "Outstanding"
author: "Frederik"
}
}
\endcode
You provide title and size of a column header
by adding a \l TableViewColumn as demonstrated below.
\code
TableView {
TableViewColumn {
role: "title"
title: "Title"
width: 100
}
TableViewColumn {
role: "author"
title: "Author"
width: 200
}
model: libraryModel
}
\endcode
The header sections are attached to values in the \l model by defining
the model role they attach to. Each property in the model will
then be shown in their corresponding column.
You can customize the look by overriding the \l itemDelegate,
\l rowDelegate, or \l headerDelegate properties.
The view itself does not provide sorting. This has to
be done on the model itself. However you can provide sorting
on the model, and enable sort indicators on headers.
\list
\li int sortIndicatorColumn - The index of the current sort column
\li bool sortIndicatorVisible - Whether the sort indicator should be enabled
\li enum sortIndicatorOrder - Qt.AscendingOrder or Qt.DescendingOrder depending on state
\endlist
You can create a custom appearance for a TableView by
assigning a \l {QtQuick.Controls.Styles::TableViewStyle}{TableViewStyle}.

This property holds the model providing data for the table view.
The model provides the set of data that is used to create the items in the view.

or provided by C++ model classes. \sa ListView::model
Example model:

ListElement{ column1: "value 3" ; column2: "value 4" }

Positions the view such that the specified \a row is at the position defined by \a mode:

\li ListView.Center - position item in the center of the view.
\li ListView.End - position item at bottom of the view.

\li ListView.Contain - ensure the entire item is visible. If the item is larger than the view the item is positioned
at the top of the view.

If positioning the \a row creates an empty space at the beginning

For example, to position the view at the end at startup:

Depending on how the model is populated, the model may not be ready when

tableview.selection.deselect(0, 1) // deselects row index 0 and 1
tableview.selection.deselect(2) // deselects row index 2

\since QtQuick.Controls 1.1
This enum indicates how the view responds to user selections:
The possible modes are:

\li SelectionMode.NoSelection - Items cannot be selected.
\li SelectionMode.SingleSelection - When the user selects an item,
any already-selected item becomes unselected, and the user cannot
unselect the selected item. (Default)
\li SelectionMode.MultiSelection - When the user selects an item in the usual way,
the selection status of that item is toggled and the other items are left alone.
\li SelectionMode.ExtendedSelection - When the user selects an item in the usual way,
the selection is cleared and the new item selected. However, if the user presses the
Ctrl key when clicking on an item, the clicked item gets toggled and all other items
are left untouched. If the user presses the Shift key while clicking
on an item, all items between the current item and the clicked item are selected or unselected,
depending on the state of the clicked item. Multiple items can be selected by dragging the
mouse over them.
\li SelectionMode.ContiguousSelection - When the user selects an item in the usual way,
the selection is cleared and the new item selected. However, if the user presses the Shift key while
clicking on an item, all items between the current item and the clicked item are selected.
