Hi,

Try the below code snippet as reference for hiding the header of the page block table:

----------- Vf page----------------

<apex:page id="page" controller="pageblocktablecolumn" >

<apex:form id="frm" >

<apex:tabPanel id="tabpanel1" switchType="client" selectedTab="name2" >

    <apex:tab label="One" name="name1" id="tabOne">

         <apex:pageBlock id="pageblock" >

     <apex:pageBlockTable id="pgtable" value="{!con}" var="cc" >

     <Apex:column ><apex:facet name="header">

     <apex:outputPanel ><apex:inputtext /><apex:commandButton value="txt"/></Apex:outputPanel>

     </apex:facet> {!cc.name}</apex:column>

     </apex:pageBlockTable>

 </apex:pageBlock>

    </apex:tab>

    <apex:tab label="Two" name="name2" id="tabTwo">content for tab two</apex:tab>

    </apex:tabPanel>

 </Apex:form>

 <Script>

var hide= true;

function hideRows(tableId){

var t = document.getElementById(tableId);

var len = t.rows.length;

var rowStyle = (hide)? "none":"";

for(i=1 ; i< len; i++){

t.rows[0].style.display = rowStyle;

}

}

hideRows('page:frm:pageblock:pgtable'); // Pass complete id of the pageblocktable

 </script>

</apex:page>

--------------- Apex controller-----------------

public class pageblocktablecolumn

{

public list<contact> con{get;set;}

public pageblocktablecolumn ()

{

    con=[select id, name from contact limit 1000];

}

}
