Row numbering with p:dataTable

Question

I have this query:

SELECT @rownum:=@rownum+1 \'no\', m.title, m.author, REPLACE(SUBSTRING_INDEX(m.content, \' \', 20), \'
\', \' \'), m.viewed, m.ha         


        

Answer 1

I am not quite sure whether you want a "numbering column" or "column numbering". I assume the first ;-)

Can't you use rowIndexVar? The Primefaces doc says:

rowIndexVar = Variable name referring to the rowIndex being processed.

This works for me:

<p:dataTable value="#{testBean.selectOptions}" rowIndexVar="rowIndex" var="item">
    <p:column headerText="#">
        #{rowIndex+1}
    </p:column>
    <p:column headerText="Option">
        #{item}
    </p:column>
</p:dataTable>

The +1 is for starting with number 1.

UPDATE:

This code produces:
