Primefaces roweditor in same column with other buttons

I have datatable in which I use roweditor. Everything works fine but I need to add few more buttons in column in which I have pencil button for editing. That "other" button is always below pencil. I've tried <p:panelgrid columns="3"... but when I did that row edithing wasn't possible. I suppose that the problem is with the other two buttons that come with row editing, (ui-icon-check and ui-icon-close). Can anyone give me an idea?
Here is my datatable:

        <p:dataTable id="sifarnikTable" rowIndexVar="rowIndex" 
            value="#{attrsBean.listOfDataBeans}" editable="true" 
            selectionMode="multiple" selection="#{attrsBean.selektovani}"
            widgetVar="datatableWidget" var="row" rowKey="#{row.primaryKey}"
            paginator="true" paginatorPosition="bottom" 
            paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink}"
            currentPageReportTemplate="{startRecord} - {endRecord} / {totalRecords}"
            emptyMessage="#{messages['datatable.emptymessage']}" rows="15"
            sortMode="multiple" paginatorAlwaysVisible="false" 
            filteredValue="#{attrsBean.filteredDatatableList}">
            <f:facet name="header">
                #{resources['db_parametri.title']}
            </f:facet>

            <p:ajax event="rowSelect" />
            <p:ajax event="rowUnselect" />

            <p:ajax event="rowEdit" listener="#{attrsBean.onEdit}"
                update=":aswdatatable:form:messages, :aswdatatable:form:sifarnikTable, :aswdatatable:form:noviBtn" />

            <p:ajax event="rowEditCancel" listener="#{attrsBean.onCancel}"
                update=":aswdatatable:form:messages" />

            <p:columns id="columns" var="column" value="#{attrsBean.columns}" 
                style="#{column.css}" width="#{column.width}"
                sortBy="#{row[column.property]}"

                filterBy="#{attrsBean.showFilter==false ? null : row[column.property]}">

                    <f:facet name="input">

                                <p:commandLink id="deleteBtn"
                                    onclick="datatableWidget.unselectAllRows();datatableWidget.selectRow(#{rowIndex}, false);brisanjeWidget.show()"
                                    process="@this"
                                    update=":aswdatatable:form:brisanjeDisplay, :aswdatatable:form:sifarnikTable"
