Yes...there are actually three cases that occur to me:
1) don't care about order, but want one row for each key (1st value)
2) do care about order, and don't want disjoint runs of dupl
on a second read ... I see that you mean the case that should only
join consecutive lines with the same key

I think the original version works just as well for both cases. Your
sed version however does need the order you mention.

hi every body,
I have two columns in a file separted by tabs
If the column1 is common in the row1 and row2 then it should be column 2
should be displayed in the single line.
eg:
col 1 col2
A1
A2
A3
B1
C 2
D 3
