When i add the following to a report element in my .jrxml file:
<property name="net.sf.jasperreports.export.xls.auto.fit.column" value="true"/>
And then i export to standard XLS, columns are auto sized appropriately. However, if I export to XSLX, this property has no effect.
I have tried:
<property name="net.sf.jasperreports.export.xlsx.auto.fit.column" value="true"/>
just to be sure, and that does not seem to do anything.
