                    <apex:commandButton reRender="error,blocktable,buttons" action="{!Cancel}" value="Cancel"/>
                    <apex:inputHidden />

                    <apex:pageBlockTable value="{!accountvar}" var="t">

                            <apex:column headerValue="AccountName" value="{!t.Name}"/ >

                            <apex:column headerValue="Phone" value="{!t.Phone}"/>
                            <apex:column headerValue="Type" value="{!t.Type}"/>                   
                            <apex:column headerValue="Account Owner Alias" value="{!t.Owner.Name}"/>
                            <apex:column headerValue="Website" value="{!t.Website}"/>

                        <apex:inlineEditSupport event="onClick"/>
