Tips and Tricks : Make apex:column value display conditionally
When try to make apex:column display conditionally there high possibility we try to code like below which will prompt Syntax error. Missing ')' .Unfortunately this is documented in any where so far.
apex:column cannot being rendered directly in value tag but we can render it different way like below
The render is done not in value tag in column but use render tag in component like outputText, outputField inside apex:column. Note that using outputField for lookup field will generate standard mini page layout when we mouse over on the link.
<apex:column headerValue="Actual Approver" value="{!IF(item.objectType=='Qualification',item.bid.Actual_Final_Approver__c,item.quote.Actual_Final_Approver__c)}"></apex:column>
