Remove space from null fields in report with JasperReport

  • 772

I am making a report with JasperReport, some columns of my MySQL table have 'null' values, I manage to control this value and not show it by assigning the property .blankWhenNull = truein the field properties. However, the white space is kept, that is, the field that is empty is hidden, but the space of the field is still there, how could I make that space disappear and loop through the fields that contain data? I tried it with a print property; So:

<printWhenExpression><![CDATA[$F{field} != null]]></printWhenExpression>

But I get the same result as when I use .blankWhenNull. Similarly, I assigned the property isBlankWhenNull="true" without success. I appreciate any input.

I show you how to print it:

    In the end, I didn't find a solution for this problem, so I had to improvise. What I did was create sub-reports to fill in that gap and that's how it worked.
