What is the best way to use composite components for columns of data table?

I have two composite components with <h:dataTable> inside and they are differ only by content of a few <h:column> What is the best way to escape copy-paste with possibilities of composite components? I know about tags, but we have no any tag in my project. So, it's not solution for me.

Add an attribute to your composite component:

<cc:interface>
    <cc:attribute name="columnType" type="java.lang.String" required="true" />
</cc:interface>

Then in the implementation

 <h:column rendered="#{cc.attrs.columnType eq 'typeAColumns'>
     #{data.valueForColumnTypeA}
 </h:column>
 <h:column rendered="#{cc.attrs.columnType eq 'typeBColumns'>
     #{data.valueForColumnTypeB}
 </h:column>

You can then use it like

 <my:compositeTable columnType="typeAColumns"/>
 <my:compositeTable columnType="typeBColumns"/>
