How to set colspan and rowspan in JSF panelGrid?

Question

How can I set colspan and rowspan in JSF ?

Answer 1

Assume

1. a message resource file with two entries:

   key.row=
key.gt=>

2. row.xhtml

   then, for example

   
     
     
     
   
     
       
       
   
       
   Hello!!!!!
     
   

Prints a table with 3 rows:

1. r1-c1, r1-c2 , r1-c3

2. 3 blank cells

3. a cell aligned center, having colspan 3 and containing a hello div.
