Code:
awk '!$0{print;next}{printf $0"\t"}' infile

and yeah, the headers you can echo it or print them in the BEGIN block of awk.

Thanks Ahamed. Could you explain a bit on the script you posted ? This is simple but quite powerful

Code:
awk '{$1=$1}1' RS="\n\n" file

Normal record selector RS is a single new line.
I do set it to two new line (as a blank line would give) RS="\n\n"
Then I do tell awk to reconstruct the data using new RS with $1=$1
Last, print everything out 1

There you go...
Code:
awk '
        {printf $0"\t"}         #Print each line without a newline separated by tab
        !$0{print;next}         #If there is an empty line, then print it with new line, this is 
                                #what basically separates the records
' infile
