    public class QTableWidget

extends QTableView

The QTableWidget class provides an item-based table view with a default model. Table widgets provide standard table display facilities for applications. The items in a QTableWidget are provided by `QTableWidgetItem`.

If you want a table that uses your own data model you should use `QTableView` rather than this class.

Table widgets can be constructed with the required numbers of rows and columns:

            tableWidget = new QTableWidget(12, 3, this);

Alternatively, tables can be constructed without a given size and resized later:

            tableWidget = new QTableWidget(this);

            tableWidget.setRowCount(10);
            tableWidget.setColumnCount(5);

Items are created ouside the table (with no parent widget) and inserted into the table with `setItem()`:

            QTableWidgetItem newItem = new QTableWidgetItem("" + (row+1) + ", " + (column+1));
            tableWidget.setItem(row, column, newItem);

If you want to enable sorting in your table widget, do so after you have populated it with items, otherwise sorting may interfere with the insertion order (see `setItem()` for details).

Tables can be given both horizontal and vertical headers. The simplest way to create the headers is to supply a list of strings to the `setHorizontalHeaderLabels()` and `setVerticalHeaderLabels()` functions. These will provide simple textual headers for the table's columns and rows. More sophisticated headers can be created from existing table items that are usually constructed outside the table. For example, we can construct a table item with an icon and aligned text, and use it as the header for a particular column:

            QTableWidgetItem cubesHeaderItem = new QTableWidgetItem(tr("Cubes"));
            cubesHeaderItem.setIcon(new QIcon(new QPixmap("classpath:images/cubed.png")));
            cubesHeaderItem.setTextAlignment(Qt.AlignmentFlag.AlignVCenter.value());

The number of rows in the table can be found with `rowCount()`, and the number of columns with `columnCount()`. The table can be cleared with the `clear()` function.

  Sets the item for the given `row` and `column` to `item`.

  The table takes ownership of the item.

  Note that if sorting is enabled (see `sortingEnabled`) and `column` is the current sort column, the `row` will be moved to the sorted position determined by `item`.

  If you want to set several items of a particular row (say, by calling `setItem()` in a loop), you may want to turn off sorting before doing so, and turn it back on afterwards; this will allow you to use the same `row` argument for all items in the same row (i.e. `setItem()` will not move the row).

See also:
  `item()`, and `takeItem()`.

### setItemPrototype

    public final void setItemPrototype(QTableWidgetItem item)

  Sets the item prototype for the table to the specified `item`.

  The table widget will use the item prototype clone function when it needs to create a new table item. For example when the user is editing editing in an empty cell. This is useful when you have a `QTableWidgetItem` subclass and want to make sure that QTableWidget creates instances of your subclass.

  The table takes ownership of the prototype.

See also:
  `itemPrototype()`.
