Designing reports for excel output with Tribix emitter

Greetings!

Recently I've been asked to generate reports with an xls output. After trying some different emitters, I ended up going with Tribix since it could manage images and seemed to generate everything almost exactly the same as defined in the .rptdesign, but then I realized that it uses a lot of empty rows and columns for the indentation to simulate padding (at least thats what I've found out so far) and that there are some elements that it doesn't display in its full width (like labels with long text).

I was wondering if there is any documentation about what to do to avoid that kind of "issues" when generating xls files with Tribix? like tips or anything alike. Also, I would like to know if there is a way to display a label (or cell content in this case) completely without the need to resize later the column's width, is there any property that could help? (I have tried the excelOptions.setOption("fixed_column_width", true); and xlsConfig.put("fixed_column_width", new Integer(100)); but apparently that doesn't help much)

Thanks!
