getting inputText on only the first row of a (Primefaces) dataTable, with dynamic columns and rows

Question

I have a Primefaces (5.0) Datatable with dynamic columns as well as dynamic rows. In brief, my problem is how do I set it up so that the cells of the first row are a series of i

Answer 1

Thank you again to Unknown: This is effectively your answer (I don't know if there is a more formal way of attributing it to you, but I am happy to do so ). Much appreciated. xhtml code as follows:

            
                                        #{rowMap[columnName]}
                                    
            
                #{columnName}
                
                
            
          

So it is as you described it for the rows, plus I have added an extra p:columns block just to differentiate the first column, and placed a columnIndexVar with rendered="#{col!=0}" conditional on the main p:Columns block so that the first column does not have the inputTextarea that the other cells of the first row do.
