Description Problem: In an SSRS matrix report with multiple column groups - all of the column group's column widths are inheriting their min-widths from the first column group header. So if the first parent column has more child group items than the other parents, all parent columns rendered as wide as the first resulting in a lot of wasted space. The problem is occuring in even the simplest matrix reports. See attachment for a wizard generated report showing this issue.
