How to destroy/hide column header in sap/m/table?

Hi All,

I want to display data in a table but I don't want to show any header .A header should be completely hidden.

Is there any property to do that??

Here's my code,

<Table id="idcompallowancetable" items="{/Added_AllowancesSet}">

<columns id="idtablecomp" >

<Column demandPopin="true">

<Label text="" />

</Column>

<Column demandPopin="true">

<Label text="" />

</Column>

Please suggest.
