Primefaces. Datatable width auto

So, I have a problem with my datatable width. I use actual version of PF: 5.1.

When I try to set width: auto and scrollable = true I have problem whit table header alignment.

|Header 1____|Header 2____|Header3_____|

|Column 1____|Column 2________|Column 3_________|

My code:

        <p:dataTable value="#{cc.attrs.rowList}"
                     var="row"
                     scrollable="true"
                     tableStyle="font-size: 13px;
                                 width: auto;
                                 min-width: 100%;">
            <p:columns value="#{cc.attrs.headerList}"
                       var="column">
                <f:facet name="header">
                    #{column.name}
                </f:facet>
                <h:outputText value="#{row[column.name]}"/>
            </p:columns>
        </p:dataTable>
