* TTableCell class.
|

|
15 |
*
|
|
|
16 |
* TTableCell displays a table cell on a Web page. Content of the table cell
|
|
|
17 |
* is specified by the {@link setText Text} property. If {@link setText Text}
|
|
|
18 |
* is empty, the body contents enclosed by the table cell component tag are rendered.
|
|
|
19 |
* Note, {@link setText Text} is not HTML-encoded when displayed. So make sure
|
|
|
20 |
* it does not contain dangerous characters.
|
|
|
21 |
*
|
|
|
22 |
* The horizontal and vertical alignments of the contents in the cell
|
|
|
23 |
* are specified via {@link setHorizontalAlign HorizontalAlign} and
|
|
|
24 |
* {@link setVerticalAlign VerticalAlign} properties, respectively.
|
|
|
25 |
*
|
|
|
26 |
* The colspan and rowspan of the cell are specified via {@link setColumnSpan ColumnSpan}
|
|
|
27 |
* and {@link setRowSpan RowSpan} properties. And the {@link setWrap Wrap} property
|
|
|
28 |
* indicates whether the contents in the cell should be wrapped.
