TTableCell displays a table cell on a Web page. Content of the table cell
is specified by the {@link setText Text} property. If {@link setText Text}
is empty, the body contents enclosed by the table cell component tag are rendered.
Note, {@link setText Text} is not HTML-encoded when displayed. So make sure
it does not contain dangerous characters.
The horizontal and vertical alignments of the contents in the cell
are specified via {@link setHorizontalAlign HorizontalAlign} and
{@link setVerticalAlign VerticalAlign} properties, respectively.
The colspan and rowspan of the cell are specified via {@link setColumnSpan ColumnSpan}
and {@link setRowSpan RowSpan} properties. And the {@link setWrap Wrap} property
indicates whether the contents in the cell should be wrapped.
