what i have to do, help me

I'd use awk, not sed, as it is easier to understand.

However, since most of the necessary is already done, I'll just add another couple of lines:

sed -n -e "/Brown/,/<\/table>/p" 11305106082.html |
sed "/Register/d;/Name/d;/blue/d;/^$/d;s/> />/g;s/^[ \t]*//;s/[ \t]*$//" |
sed -e :a -e N -e "s/<\/td>\n/,/;s/<\/th>\n/,/" -e ta |
sed -e :a -e "s/<[^>]*>//g;/</N;//ba" |
sed "/^$/d" | {
 read line
 sed  "/.../ s/^/$line/"
}


perl -ne 'if($.==1){$_ =~ tr/\n//d;$t=$_;}else{print $t,$_;}' file

Thank you Mr. johnson.

awk '{
if(NR==1)
	t=$0
else
	print t""$0
}' file
