How can I align to right the column grid?

Example of display data     
    TEXT         TOTAL
     text?1    585
     text?1    1.185
     text?1    2
It should be:
    TEXT         TOTAL
     text?1      585
     text?1    1.185
     text?1        2
     

styleClass property don´t apply en thesource code

    <td class="igGridColumn">1.148</td>

Example of code

<ig:gridView id="grid_processesList"
    dataSource="#{ProcessesListBean.processesList}"
    binding="#{ProcessesListBean.processesListGridView}"
    pageSize="#{configurationWeb.processesList_pageSize}"
    bottomPagerRendered="true" topPagerRendered="false"
    dataKeyName="id"
    selectedRowsChangeListener="#{ProcessesListBean.onSelectedRowsChange}"
    resizableColumns="true">
   
   
    <f:facet name="header">
        <h:outputText value="tableHeader" />
    </f:facet>
...           
    <ig:column styleClass="right">
        <f:facet name="header">
            <h:outputText value="TOTAL" />
        </f:facet>
        <h:outputText value="#{DATA_ROW.docsTotal }">
            <f:convertNumber type="number" pattern="#,##0"
                groupingUsed="true" />
        </h:outputText>
    </ig:column>
           
Thanks
