public class WTable extends WInteractWidget
A container widget which provides layout of children in a table grid.

A WTable arranges its children in a table.

To insert or access contents, use getElementAt() to access the cell at a particular location in the table. The WTable expands automatically to create the indexed (row, column) as necessary.

It is possible to insert and delete entire rows or columns from the table using the insertColumn(int column), insertRow(int row), deleteColumn(int column), or deleteRow(int row) methods.

You may indicate a number of rows and columns that act as headers using setHeaderCount(). Header cells are rendered as <th> instead of <td> elements. By default, no rows or columns are configured as headers.

WTable is displayed as a block.

CSS

The widget corresponds to the HTML <table> tag and does not provide styling. It can be styled using inline or external CSS as appropriate.

      public WTableCell getElementAt(int row, int column)
      Accesses the table element at the given row and column.

      If the row/column is beyond the current table dimensions, then the table is expanded automatically.

    • getRowAt

      public WTableRow getRowAt(int row)
      Returns the row object for the given row.

      Like with getElementAt(), the table expands automatically when the row is beyond the current table dimensions.

      See Also:

    • getColumnAt

      public WTableColumn getColumnAt(int column)
      Returns the column object for the given column.

      Like with getElementAt(), the table expands automatically when the column is beyond the current table dimensions.

      See Also:

    • removeCell

      public void removeCell(WTableCell item)
      Deletes a table cell and its contents.

      The table cell at that position is recreated.

      See Also:

    • removeCell

      public void removeCell(int row, int column)
      Deletes the table cell at the given position.

      Inserts a row.

      Returns insertRow(row, null)

    • removeRow

      public WTableRow removeRow(int row)
      Removes a row.

      Rows below the given row are shifted up. Returns a WTableRow that is not associated with a WTable. Unlinke removeColumn(), the cells in the row will not be deleted, because they are owned by the WTableRow.

    • insertColumn

      public WTableColumn insertColumn(int column, WTableColumn tableColumn)
      Inserts an empty column.

    • insertColumn

      public final WTableColumn insertColumn(int column)

    • removeColumn

      public WTableColumn removeColumn(int column)
      Remove a column and all its contents.

      The contents of the column will be deleted, because a WTableColumn does not own its cells.
