    <apex:pageBlock title="My Content">
        
        <value="{!sspList}" var="item">
        <apex:column  value="{!item.Service_Partner__c}"/>
        <apex:column value="{!item.Contracted_Services__c}"/>
        <apex:column value="{!item.Primary_Field_Contact__c}"/>
        <apex:column value="{!item.Primary_Field_Mobile__c}"/>  
        <apex:column value="{!item.Primary_Field_Email__c}"/>
