What if the source/ columns is dynamic generated?
The normal source generated usually would be, for instance,
'List<Customer>'. So the column name mapping to the entity attribute can be
rendered automatically by 'Contrib:Table' However, if the column name and
table content are generated dynamically. What kind of format I need to put
inside the source? This is my question.
My second question is - does the Contrib:Table can render aggregative cell
inside a table?
For instance, it looks like the html code
<table>
<!-- beg -->
<tr>
<td rowspan="4">date</td>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
</tr>
<!--- end -->
</table>
Stuff between 'beg' and 'end' would be treated as a set (like Customer in
the List). Then repeatly rendering the set. How can I achieve it?
The tapestry I use is 4.0.x. Java 1.6.x. Jboss 4.2.2
