* TLiteralColumn represents a static text column that is bound to a field in a data source.
|
|
|
22 |
* The cells in the column will be displayed with static texts using the data indexed by
|
|
|
23 |
* {@link setDataField DataField}. You can customize the display by
|
|
|
24 |
* setting {@link setDataFormatString DataFormatString}.
|
|
|
25 |
*
|
|
|
26 |
* If {@link setDataField DataField} is not specified, the cells will be filled
|
|
|
27 |
* with {@link setText Text}.
|
|
|
28 |
*
|
|
|
29 |
* If {@link setEncode Encode} is true, the static texts will be HTML-encoded.
