/**
* The Table widget displays a table of items, each with a text and optional
* icon.  A column Header control provide captions for each column, and a row
* Header control provides captions for each row.  Columns are resizable by
* means of the column Header control if the TABLE_COL_SIZABLE option is passed.
* Likewise, rows in the table are resizable if the TABLE_ROW_SIZABLE option is
* specified.  An entire row (column) can be selected by clicking on the a button
* in the row (column) Header control.  Passing TABLE_NO_COLSELECT disables column
* selection, and passing TABLE_NO_ROWSELECT disables column selection.
* When setColumnRenumbering() is called, column captions are automatically renumbered
* when columns are added or removed, according to the label computed by the renumbering
* function.  Likewise, setRowRenumbering() will cause row numbers to be recalculated
* automatically when rows are added or removed.  The column and row renumbering
* functions to not have to be the same.  Passing a NULL renumbering function will
* turn automatic renumbering off; this is the default.
* To disable editing of cells in the table, the TABLE_READONLY can be specified.
* Cells in the table may or may not have items in them.  When populating a cell
* for the first time, an item will be automatically created if necessary.  Thus,
* a cell in the table takes no space unless it has actual contents.
* Moreover, a contiguous, rectangular region of cells in the table may refer to
* one single item; in that case, the item will be stretched to cover all the
* cells in the region, and no grid lines will be drawn interior to the spanning
* item.
* The Table widget issues SEL_SELECTED or SEL_DESELECTED when cells are selected
* or deselected, respectively.  The table position affected is passed along as the
* 3rd parameter of these messages.
* Whenever the current (focus) item is changed, a SEL_CHANGED message is sent with
* the new table position as a parameter.
* When items are added to the table, a SEL_INSERTED message is sent, with the table
* range of the newly added cells as the parameter in the message.
* When items are removed from the table, a SEL_DELETED message is sent prior to the
* removal of the items, and the table range of the removed cells is passed as a parameter.
* A SEL_REPLACED message is sent when the contents of a cell are changed, either through
* editing or by other means; the parameter is the range of affected cells.  This message
* is sent prior to the change.
* SEL_CLICKED, SEL_DOUBLECLICKED, and SEL_TRIPLECLICKED messages are sent when a cell
* is clicked, double-clicked, or triple-clicked, respectively.
* A SEL_COMMAND is sent when an enabled item is clicked inside the table.
