# Class TableColumn<S,​T>

java.lang.Object
javafx.scene.control.TableColumnBase<S,​T>
javafx.scene.control.TableColumn<S,​T>

Type Parameters:
  `S` - The type of the TableView generic type (i.e. S == TableView<S>)
  `T` - The type of the content in all cells in this TableColumn.

All Implemented Interfaces:
  `Styleable`, `EventTarget`

    public class TableColumn<S,​T>
    extends TableColumnBase<S,​T>
    implements EventTarget

A `TableView` is made up of a number of TableColumn instances. Each TableColumn in a table is responsible for displaying (and editing) the contents of that column. As well as being responsible for displaying and editing data for a single column, a TableColumn also contains the necessary properties to:

- Be resized (using `minWidth`/`prefWidth`/`maxWidth` and `width` properties)
- Have its `visibility` toggled
- Display `header text`
- Display any `nested columns` it may contain
- Have a `context menu` when the user right-clicks the column header area
- Have the contents of the table be sorted (using `comparator`, `sortable` and `sortType`)

When creating a TableColumn instance, perhaps the two most important properties to set are the column `text` (what to show in the column header area), and the column `cell value factory` (which is used to populate individual cells in the column). This can be achieved using some variation on the following code:

     ObservableList<Person> data = ...
     TableView<Person> tableView = new TableView<Person>(data);

     TableColumn<Person,String> firstNameCol = new TableColumn<Person,String>("First Name");
     firstNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
         public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
             // p.getValue() returns the Person instance for a particular TableView row
             return p.getValue().firstNameProperty();
         }
      });

     tableView.getColumns().add(firstNameCol);}

This approach assumes that the object returned from `p.getValue()` has a JavaFX `ObservableValue` that can simply be returned. The benefit of this is that the TableView will internally create bindings to ensure that, should the returned `ObservableValue` change, the cell contents will be automatically refreshed.

In situations where a TableColumn must interact with classes created before JavaFX, or that generally do not wish to use JavaFX apis for properties, it is possible to wrap the returned value in a `ReadOnlyObjectWrapper` instance. For example:

     firstNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
         public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
             return new ReadOnlyObjectWrapper(p.getValue().getFirstName());
         }
      });

It is hoped that over time there will be convenience cell value factories developed and made available to developers. As of the JavaFX 2.0 release, there is one such convenience class: `PropertyValueFactory`. This class removes the need to write the code above, instead relying on reflection to look up a given property from a String. Refer to the `PropertyValueFactory` class documentation for more information on how to use this with a TableColumn. Finally, for more detail on how to use TableColumn, there is further documentation in the `TableView` class documentation.

  JavaFX 2.0

  - ### tableView

    public final ReadOnlyObjectProperty<TableView<S>> tableViewProperty
    The TableView that this TableColumn belongs to.
    See Also:
      `getTableView()`

  - ### cellValueFactory

    public final ObjectProperty<Callback<TableColumn.CellDataFeatures<S,​T>,​ObservableValue<T>>> cellValueFactoryProperty
    The cell value factory needs to be set to specify how to populate all cells within a single TableColumn. A cell value factory is a `Callback` that provides a `TableColumn.CellDataFeatures` instance, and expects an `ObservableValue` to be returned. The returned ObservableValue instance will be observed internally to allow for immediate updates to the value to be reflected on screen. An example of how to set a cell value factory is:

         lastNameCol.setCellValueFactory(new Callback<CellDataFeatures<Person, String>, ObservableValue<String>>() {
             public ObservableValue<String> call(CellDataFeatures<Person, String> p) {
                 // p.getValue() returns the Person instance for a particular TableView row
                 return p.getValue().lastNameProperty();
             }
          });
         }

    A common approach is to want to populate cells in a TableColumn using a single value from a Java bean. To support this common scenario, there is the `PropertyValueFactory` class. Refer to this class for more information on how to use it, but briefly here is how the above use case could be simplified using the PropertyValueFactory class:

         lastNameCol.setCellValueFactory(new PropertyValueFactory<Person,String>("lastName"));

    See Also:
      `getCellValueFactory()`, `setCellValueFactory(Callback)`

  - ### cellFactory

    public final ObjectProperty<Callback<TableColumn<S,​T>,​TableCell<S,​T>>> cellFactoryProperty
    The cell factory for all cells in this column. The cell factory is responsible for rendering the data contained within each `TableCell` for a single table column.

    By default, `TableColumn` uses the `default cell factory`, but this can be replaced with a custom implementation, for example, to show data in a different way or to support editing. There is a lot of documentation on creating custom cell factories elsewhere (see `Cell` and `TableView` for example).

    Finally, there are a number of pre-built cell factories available in the `javafx.scene.control.cell` package.

    See Also:
      `getCellFactory()`, `setCellFactory(Callback)`

  - ### sortType

    public final ObjectProperty<TableColumn.SortType> sortTypeProperty
    Used to state whether this column, if it is part of a sort order (see `TableView.getSortOrder()` for more details), should be sorted in ascending or descending order. Simply toggling this property will result in the sort order changing in the TableView, assuming of course that this column is in the sortOrder ObservableList to begin with.
    See Also:
      `getSortType()`, `setSortType(TableColumn.SortType)`

  - ### onEditStart

    public final ObjectProperty<EventHandler<TableColumn.CellEditEvent<S,​T>>> onEditStartProperty
    This event handler will be fired when the user successfully initiates editing.
    See Also:
      `getOnEditStart()`, `setOnEditStart(EventHandler)`

  - ### onEditCommit

    public final ObjectProperty<EventHandler<TableColumn.CellEditEvent<S,​T>>> onEditCommitProperty
    This event handler will be fired when the user successfully commits their editing.
    See Also:
      `getOnEditCommit()`, `setOnEditCommit(EventHandler)`

  - ### onEditCancel

    public final ObjectProperty<EventHandler<TableColumn.CellEditEvent<S,​T>>> onEditCancelProperty
    This event handler will be fired when the user cancels editing a cell.
    See Also:
      `getOnEditCancel()`, `setOnEditCancel(EventHandler)`

- ## Field Details

  - ### DEFAULT_CELL_FACTORY

    public static final Callback<TableColumn<?,​?>,​TableCell<?,​?>> DEFAULT_CELL_FACTORY
    If no cellFactory is specified on a TableColumn instance, then this one will be used by default. At present it simply renders the TableCell item property within the `graphic` property if the `item` is a Node, or it simply calls `toString()` if it is not null, setting the resulting string inside the `text` property.

- ## Constructor Details

  - ### TableColumn

    public TableColumn()
    Creates a default TableColumn with default cell factory, comparator, and onEditCommit implementation.

  - ### TableColumn

    public TableColumn​(String text)
    Creates a TableColumn with the text set to the provided string, with default cell factory, comparator, and onEditCommit implementation.
