Attribute	Description

`for="id"`	Identifies the iterator control. If this simple action is nested in a repeating control, that control is the default.
`loaded="true\|false"`	Creates a tag instance when the control is loaded, or not. Defaults to `true`.
`rowCount="number"`	Number of rows to add. Defaults to the number of rows displayed on each page of the iterator.
`state="true\|false"`	If the server state should be saved after getting the AJAX request.

Examples

Here a button at the bottom of a data table adds three rows per click.

<xp:dataTable id="dataTable1" rows="10" value="#{javascript:return database.getAllDocuments()}" var="rowdoc">
	<xp:column id="column1">
		<xp:this.facets>
			<xp:label value="subject" id="label1" xp:key="header" style="font-weight:bold"></xp:label>
		</xp:this.facets>
		<xp:text escape="true" id="computedField1">
			<xp:this.value>
				<![CDATA[#{javascript:return rowdoc.getItemValueString("subject")}]]>
			</xp:this.value>
		</xp:text>
	</xp:column>
</xp:dataTable>

<xp:button value="Add 3 rows" id="button1">
	<xp:eventHandler event="onclick" submit="false">
		<xp:this.script>
