    You can try like this :

    <p:dataTable value="#{tabulky.tabulka.sheet}"
             var="item"
             scrollable="true"
             height="500"
             emptyMessage=" Ziadne data nenajdene &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;">
    <f:facet name="header">
        <h:outputText value="Listocky"/>
    </f:facet>
    <p:column>
        <f:facet name="header">
            <h:outputText value="#{item}"/>
        </f:facet>
        <p:dataTable value="#{(item.value)}" var="item1">
            <p:column headerText="Hokej">
                <h:outputText value="#{item1.atr1}" />
            </p:column>
            <p:column>
                <h:outputText value="#{item1.atr2}" />
            </p:column>
            <p:column>
                <h:outputText value="&nbsp;:&nbsp;}" />
            </p:column>
            <p:column>
                <h:outputText value="#{item1.atr3}" /> 
            </p:column>
       </p:dataTable>
    </p:column>
</p:dataTable>

    Use the p:dataTable replace the c:forEach
