- ## Property Details

  - ### tableColumn

    public final ReadOnlyObjectProperty<TableColumnBase<?,?>> tableColumnProperty
    A property that refers to the `TableColumnBase` instance that this header is visually represents.
    See Also:
      - `getTableColumn()`
      - `tableColumnProperty()`

- ## Constructor Details

  - ### TableColumnHeader

    public TableColumnHeader(TableColumnBase tc)
    Creates a new TableColumnHeader instance to visually represent the given `TableColumnBase` instance.
    Parameters:
      `tc` - The table column to be visually represented by this instance.

- ## Method Details

  - ### getTableColumn

    public final TableColumnBase<?,?> getTableColumn()
    Gets the value of the `tableColumn` property.
    Property description:
      A property that refers to the `TableColumnBase` instance that this header is visually represents.
    Returns:
      the value of the `tableColumn` property
    See Also:
      - `tableColumnProperty()`

  - ### tableColumnProperty

    public final ReadOnlyObjectProperty<TableColumnBase<?,?>> tableColumnProperty()
    A property that refers to the `TableColumnBase` instance that this header is visually represents.
    Returns:
      the `tableColumn` property
    See Also:
      - `getTableColumn()`

  - ### getTableHeaderRow

    protected TableHeaderRow getTableHeaderRow()
    Returns the `TableHeaderRow` associated with this `TableColumnHeader`.
    Returns:
      the `TableHeaderRow` associated with this `TableColumnHeader`
    Since:
      12

  - ### getTableSkin

    protected TableViewSkinBase<?,?,?,?,?> getTableSkin()
    Returns the `TableViewSkinBase` in which this `TableColumnHeader` is inserted. This will return `null` until the `TableHeaderRow` has been set.
    Returns:
      the `TableViewSkinBase` in which this `TableColumnHeader` is inserted, or `null`
    Since:
      12

  - ### resizeColumnToFitContent

    protected void resizeColumnToFitContent(int maxRows)
    Resizes this `TableColumnHeader`'s column to fit the width of its content.
    Implementation Requirements:
      The resulting column width for this implementation is the maximum of the preferred width of the header cell and the preferred width of the first `maxRow` cells.

      Subclasses can either use this method or override it (without the need to call `super()`) to provide their custom implementation (such as ones that exclude the header, exclude `null` content, compute the minimum width, etc.).

    Parameters:
      `maxRows` - the number of rows considered when resizing. If -1 is given, all rows are considered.
    Since:
      14

  - ### getClassCssMetaData

    public static List<CssMetaData<? extends Styleable, ?>> getClassCssMetaData()
    Returns the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.
    Returns:
      the CssMetaData associated with this class, which may include the CssMetaData of its superclasses
