[XXE] problem with Process instruction

[Stephane Le Deaut]

Hello,

I am using the spreadsheet engine integrated in XXE.

My problem is the following :
I am trying to link cells in a table.
if the cell contains one line it works fine. For example :
table
        tgroup
                tbody
                        row (1)
                                entry (A)               entry (B)               
entry (C)
                                   1                       2                    
 = A1 + B1 = 3

Unfortunately my table contains more than one line per row see below :
                        row (2)
                                entry (A)               entry (B)               
entry (C)
                                                         para
                                   1                       2                    
 = A2 + B2 = ???
                                                         para
                                                           3

I did not find in the documentation how to manage more than one line per
row.
How to do it ? Could you give an example ?

thanks in advance for your help
