Open in new window

I want to make a header file which contains each row from column 1 as individual column headers and min - max from each of the m and present it in column format.

Info in log files:

Trace Header                Min     Max   Mean
aaa                                  1           6         xx
bbb                                  2          7         xxx

What I want :

aaa            bbb

1-6            2-7

Thanks for help
