<p:datatable value="#{tabulky.tabulka.sheet}" var="item" scrollable="true" height="500" emptymessage=" ziadne info 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> <c:foreach items="#{(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> </c:foreach> </p:column> </p:datatable>

but no success

you can seek :

<p:datatable value="#{tabulky.tabulka.sheet}" var="item" scrollable="true" height="500" emptymessage=" ziadne info 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 p:datatable replace c:foreach

java primefaces
