can we use rowspan and colspan in displaytag?

问题

I have to create a table, whose structure is like this

|--------------------------------|  
|col1|col2|      col3       |col4|  
|    |    | col3.1 | col3.2 |    |  
|----|----|--------|--------|----|  
|----|----|--------|--------|----|  

Is it possible to create such a datagrid using display tag?

回答1:

Check out the decorator examples (http://displaytag.sourceforge.net/1.2/tut_decorators.html), that is your best bet.

Another way to do it is to add the content of the cell manually, like so:

<display:column titleKey="something" media="html">

       <c:out_of_property_here>

</display:column>

If I remember correctly, if my table was defined like:

<display:table name="test" requestURI="some_uri"
    defaultsort="0" id="test" export="true" excludedParams="*" >

you would access the current element using test, so if the object you are displaying has a property id with a getter getId, you would access the current object in the list by writing test.id.

But I would try using a decorator first (you can add decorators per-column iirc), the second option is very messy.
