I am creating PDF page (in html page not working too), I have pageBlockTable in it. I need to display row number in first column. I found solution to use apex:variable and increment it.

 <apex:variable value="{!0}" var="index"/>
    <apex:pageBlockTable value="{!salesOrderItems}" var="salesOrderItem" border="1px">
        <apex:variable var="index" value="{!index + 1}"/>
        <apex:column>
            <apex:facet name="header">
                <apex:outputLabel value="Number" />
            </apex:facet>
            <apex:outputLabel value="{!index}" />
        </apex:column>
        ...
     </apex:pageBlockTable>

But in every row I see 0. Increment is not working.

The dataTable and pageBlockTable elements do weird things for content outside of apex:column elements (usually by way of ignoring the content entirely). If you put the counter inside a column, it will work:

<apex:page controller="counter">
    <apex:variable value="{!0}" var="index" />
    <apex:pageBlock>
        <apex:pageBlockTable value="{!elements}" var="element">
            <apex:column>
                <apex:outputText>
                <apex:variable value="{!index + 1}" var="index" />
                {!index}
                </apex:outputText>
            </apex:column>
        </apex:pageBlockTable>
    </apex:pageBlock>
</apex:page>

  • Thanks, this works. Your solution to do it with css - salesforce.stackexchange.com/questions/111919/… works in html, but not in PDF

    @VladyslavKushney Yeah, the CSS engine in PDF mode is a bit behind the times. I had thought there was a solution were you could increment a counter in a table, and there was actually another question recently about content appearing outside the table, which reminded me of that idiosyncrasy.

According to this page, it is unsupported.

Though most of us have used it inside of an <apex:repeat> without problems, I suspect that the VF engine works differently in an <apex:PageBlockTable> and the counter does not get incremented.
