Select portions of one column and paste as new column
Clash Royale CLAN TAG#URR8PPP
I have a file in the following format:

So the first column repeats itself, and the second column changes. They're separated by a "&" in the first column and an empty space in the second column. There might be 1000s of such sections. I'd like to cut the portion of the second column and paste it as a new column, so in this case:
# Comment
# Comment
# Comment
@ Title
@ Label
@ Label
1 2 7
2 5 4
3 7 9
Then I could graph all the columns more easily. I also don't care about the first lines, in case is easier to just remove them or leave them there, doesn't matter much.

Run it:
cat << EOF | awk '
$1 == "#" || $1 == "@" print; next
$1 != "&" result[$1] = (result[$1] ? result[$1] : $1) "t" $2
END for (i in result) print result[i]
'

Or you can use the file filename with input data. In this case run:
awk '
$1 == "#" || $1 == "@" print; next
$1 != "&" result[$1] = (result[$1] ? result[$1] : $1) "t" $2
END for (i in result) print result[i]
' filename
In both cases you'll get the result:

it works, thank you! For some reason however the output is out of order, any way to fix this? It's not a big problem since I can fix it in my spreadsheet, but it would help with my worflow. If it matters the numbers in each column can be very large and not only single digits.
