The way it worked so far, the first column was always filled to the bottom of the page before touching the second column. While this makes much sense for a phone book, the result sometimes is not optimal in terms of whitespace on the page. A typical example with LL24 might look like this:
Note the huge amount of whitespace in the right column. So a frequent request has been "can we get to print columns across-down as well?". In LL25, the answer finally is "yes".
The column configuration got a new switch "Fill horizontally":
The result is then as expected and often requested, of course:
The whitespace underneath can now be used e.g. for the next table item.
Another use case for this feature is horizontal subreports, e.g. printing the order numbers for a certain product. Sub tables now also have a column count that was not available before. Thus is this configuration
you can switch the column count for the Order Details table (which contains the order number as 1:1 relation):
Note that you don't need to change the column alignment to horizontal in this case – sub tables are always printed like this. The result then is a compact view of products and their respective order numbers:
While seemingly a small change, this enables a whole lot of new reporting scenarios. For technical reasons, the feature is currently limited to the report container, that means you need to use a report container.
