Have specified a Report putting individual fields onto a Report in a 'tabular' type style (this appeared to be the best way to handle other difficulties).
In Excel the Filtering fails due to inconsistent Cell Sizes. Obvious differences have been removed, but we still get the same problem.
I will have a good look at this to fix this. If anyone's got some helpful tips as to easiest overcome this type of difficulty that would be appreciated and save me some time.
(The output file is fairly complex and therefore we cannot heavily edit it each time we create it).
