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.
Renders body contents of the table cell.
If the text content is empty, body content (child controls) of the cell will be rendered.
