What is the best Birt xlsx emitter ?
We are migrating xlsx exports created with librabries like infragistic to Birt.
We are looking for a xlsx Birt that would allow us a degree of control on when a cell is merged or not.
I'm not speaking of the cells we can merge in the design editor or through the design api in beforeFactory.
The crosstabs merge cells with identical values automatically. And we wish to do the same thing inside tables, because some of our uses cases are too complicated for crosstabs (mix of fixed and dynamic columns, with varying dimensions hierarchies).
Also a use case where we had problem, was to get a crosstab cell to render as a merged cell in xlsx format (colspan of 2 basically).
Thanks for your advices.
