jsf primefaces datatable p:columns

ive got a Primefaces DataTable like this 

<p:dataTable
   value="#{valueList.value}"
   var="value"
   selection="#{valueList.selected}"
   id="measurementTable"
   paginator="true"
   rows="20"
   rowsPerPageTemplate="20,25,30,35,40"/>

and dynamic Columns with this

<p:columns
  value="#{valueList.columns}"
  var="column"
  columnIndexVar="colIndex"
 />

this works fine and my Datatable looks good , but when i add

  sortBy="#{value.charge}"

to p:columns and i was click on column to sort the css style is destroyd and ive got a List with my Data not a DataTable, this is very ugly.

My code 

<p:dataTable
        value="#{measurementList.measurements}"
        var="measurement"
        selection="#{measurementList.selected}"
        id="measurementTable"
        paginator="true"
        rows="20"
        rowsPerPageTemplate="20,25,30,35,40"
        rowKey="#{measurement.mdkFid}"
        emptyMessage="#{measurementList.getCapString('no_records_found')}">

        <p:column selectionMode="multiple" style="width:18px" />

        <p:column>
            <p:commandLink title="#{measurementList.getString('edit')}" update=":contentPanel">
                <h:outputText styleClass="ui-icon ui-icon-pencil" />
                <f:actionListener binding="#{measurementList.editSelected(measurement) }" />
                <f:actionListener binding="#{navigation.goTo('/xhtml/measurements/editMeasurement.xhtml') }" />
            </p:commandLink>
        </p:column>

        <p:columns
            value="#{measurementList.columns}"
            var="column"
            columnIndexVar="colIndex"
            styleClass="measurementListDatatableColumn"
            sortBy="#{column.displayName}" 
            >
            <f:facet name="header">#{column.displayName}</f:facet>
                <p:column>
                    #{measurement[column.methodName]}
                </p:column>
        </p:columns>

Your sort should look something like

sortBy="#{value[column.charge]}"

Take a look at the showcase example DataTable - Dynamic Columns

Change

 <p:columns
        value="#{measurementList.columns}"
        var="column"
        columnIndexVar="colIndex"
        styleClass="measurementListDatatableColumn"
        sortBy="#{column.displayName}" 
        >
        <f:facet name="header">#{column.displayName}</f:facet>
            <p:column>
                #{measurement[column.methodName]}
            </p:column>
    </p:columns>

into

 <p:columns
        value="#{measurementList.columns}"
        var="column"
        columnIndexVar="colIndex"
        styleClass="measurementListDatatableColumn"
        sortBy="#{measurement[column.methodName]}" 
        >
        <f:facet name="header">
            #{column.displayName}
        </f:facet>

         #{measurement[column.methodName]}

    </p:columns>

In general : the same EL expression that is used to display the data of the column , should be used for the sortBy
