I am not a programmer, but I think there is a bug here in 2.1.20. When you define HEADER and FOOTER in the XML of the REPORT, they will be displayed as defined in version 1.7.20, but in 2.1.20, only TCPDF's default lines and page numbers will be displayed。

Part of XML file:

		<SetVar name="fill" value="" />
		<if condition="$sortby=='NAME'"><SetVar name="fill" value="#AAAAAA" /></if>
		<Cell bgcolor="$fill" border="1" width="200" style="label"><var var="I18N::translate('Name')" /></Cell>

		<SetVar name="fill" value="" />
		<if condition="$sortby=='BIRT:DATE'"><SetVar name="fill" value="#AAAAAA" /></if>
		<Cell bgcolor="$fill" border="1" width="100" style="label"><var var="I18N::translate('Date')" /></Cell>

		<Cell border="1" width="150" style="label"><var var="I18N::translate('Place')" /></Cell>
		<Cell border="1" newline="1" style="label"><var var="I18N::translate('Source')" /></Cell>
	</Header>

	......
	
	
	<Footer>
		<Cell align="rightrtl" newline="1" style="date"><Now/></Cell>
	</Footer>
</Doc>

And the pdf report of 1.7.20

but ,there will have nothing in 2.1.20

Furthermore, I need to define a special HEADER as follows

So I made some modifications to implement it, but because I am not a developer, the code is not very standardized and only serves as a suggestion for reference。

Thanks.
