I want to change the background color for the first row of data in a table displayed on a visual force page. I am thinking the best way to do this is change the style based on a test of which record is being displayed. However, I'm not sure how to determine which record is being displayed. 

Here's the code in a portion of my VF page:

<apex:pageBlock >   
    <apex:pageBlockTable value="{!cRecords}" var="cRecord">
       
        <apex:column value="{!cRecord.Name}">
            <apex:facet name="header">HCC</apex:facet>
        </apex:column>
       
        <apex:column value="{!cRecord.HCC_strNum__c}">
            <apex:facet name="header">HCC</apex:facet>
        </apex:column>
       
        <apex:column value="{!cRecord.Type__c}">
            <apex:facet name="header">Type</apex:facet>
        </apex:column>
   
        <apex:column value="{!cRecord.Confidence_Level__c}">
            <apex:facet name="header">Confidence Level</apex:facet>
        </apex:column>
        </apex:pageBlockTable>
    </apex:pageBlock>

I thought the best way to do this is to use the index number of the array to determine whether to highlight the field, but I don't know how to retrieve the index number. Is there way to achieve something like the line below? I know cRecords.indexnumber = 0 is not correct/valid, but I'm looking for what that syntax might be. 

<apex:column value="{!cRecord.Name}" style="{!IF(cRecords.indexnumber = 0),"background-color: green;",""background-color: white);"
