Grouping

[ediman16]

Hello,
Can anyone help me create a macro that groups information. I have a lot of data on my worksheet and the regular way of creating groups has turned out to be slow and inefficient.
The groups shall be formed according to information in the column "E".
Thank you

To specify; I need a macro that creates groups of data that is in the column E. There are empty cells between the groups of data, thus the classic method of grouping turns out to be insufficient.
