Rendered is making my column headers disappear

Hi everyone,

So i am trying to make my empty columns disappear, and i've achieved this however, the rendered part of my code is also making my headers disappear. How would i solve this?

My code: 
<apex:pageBlock >
            <apex:pageBlockTable value="{!qli}" var ="opp">
                <apex:column  headerValue = "Device Name" value = "{!opp.Device_Name__c}" rendered="{!NOT(ISNULL(opp.Device_Name__c))}"/>
                <apex:column headerValue = "Device Type" value="{!opp.Device_Type__c}" rendered="{!NOT(ISNULL(opp.Device_Type__c))}" />
                <apex:column headerValue = "Part Number" value="{!opp.Product2.Name}" rendered="{!NOT(ISNULL(opp.Product2.Name))}" />
                <apex:column headerValue="Serial Number" value="{!opp.Serial_Number__c}" rendered="{!NOT(ISNULL(opp.Serial_Number__c))}" />
                <apex:column headerValue="Contract Start Date" value="{!opp.Contract_Start_Date__c}" rendered="{!NOT(ISNULL(opp.Contract_Start_Date__c))}"/>
                <apex:column  headerValue="Contract End Date" value="{!opp.Contract_End_Date__c}" rendered="{!NOT(ISNULL(opp.Contract_End_Date__c))}"/>
            </apex:pageBlockTable>             
      </apex:pageBlock>

See those keep the headers in if the column is empty. I want it so that it doesn't keep the empty column headers in

I decided against using pageblock table and instead utilze html tables
