数据表jsf中的一对多行？

Question

How can I create datatable which displays record as the following:

|      | SECOND |
| ONE  | THIRD  |
|      | FORTH  |
|      | FIFTH  |

eg one to many. Can you help me?

Answer 1

There's no way to achieve it with Primefaces, AFAIK. You could use a subtable instead to do something like:

|               ONE                 | 
| SECOND | THIRD  || FORTH  || FIFTH  |

Or even use a rowExpansion utility, which I usually use for most of my one to many cases.

If your requirement is to match exactly what you ask for, you could always go with a pure JSF implementation instead and try to style it using Primefaces CSS stylesheets.

Answer 2

Using subtable you can display 1 to N relation data like:

| ONE | SECOND |
|     | THIRD  |
|     | FORTH  |
|     | FIFTH  |

For that you need repeat ONE in each line, but display (rendered) it for first line only. See result using RichFaces
