Hi.

VF code:

<apex:pageBlockSection >

<apex:pageBlockTable value="{!accounts}" var="a" columns="3"  style="font-size:25px"  >

<apex:column headervalue="Customer Name" value="{!a.acc.Field3__c}"  />
<apex:column headervalue="Account Name" value="{!a.acc.Name}" />
<apex:column headervalue="Comments" value="{!a.acc.NlTokki__c}" />
</apex:pageBlockTable>

</apex:pageBlockSection>

In the above there are 3 columns in the pageblockTable.

Unable to stretch or expand the above 3 columns to a full page.

I also tired with width=" " columnsWidth="" but nothing worked.

The columns are not expanding after certain size.

I need these 3 columns to displayed equally in a full page mode.

Ideas are greatly appreciated.
