Conditional display of a column based on its data

This video how-to shows basic concepts around conditional display of a column in a Table object, based on its data.
This example is based on Jaspersoft Studio 6.0.1 but it should work (possibly with little editing) on recent releases, such as 5.x.

How to align the table to center after hiding column(s) ....?

How can we hide a row? For example: "We have to hide all rows without end_date".

Thank you. Any trick to shift neighbour column if the one is empty? My data is not 'table' format but just report.

Hi I have a Jasper report with a sub report now I want the report to display the data only if there's data on the sub-report hence the details are from the sub-report only headers from the main
I created a variable which is a 1 or 0, when this variable is 1 it means there's a data to display so I set the print when to " $V{Variable_1}.equals(1) " and it comes with a blank report I would appreciate if someone could help

also tried this $V{Variable_1}.floatValue() == 1? new Boolean(true) : new Boolean(false)

does this still work if the table is not in the summary band? I assume you put it there so it only evaluates at the report level. wondering if its possible to set the evaluation time of the print when condition in any kind of band somehow

also I'm wondering if this would still work if you have a larger number of rows returned from the query. I see you put it at limit 20, was that intentional? I seem to recall that the summary band doesn't paginate like a regular detail band
