beginner

I try to convert clean columnwise data to tables in tex. I am unable to have "\ \n" at each end of line. Please, see the command at the end.

Data

$ echo `. ./bin/addTableTexTags.sh < .data_3`
10.31 & 8.50 & 7.40 
 10.34 & 8.53 & 7.81 
 8.22 & 8.62 & 7.78 
 10.16 & 8.53 & 7.44 
 10.41 & 8.38 & 7.63 
 10.38 & 8.57 & 8.03 
 10.13 & 8.66 & 7.41 
 8.50 & 8.60 & 7.15 
 10.41 & 8.63 & 7.21 
 8.53 & 8.53 & 7.12 

$ cat .data_3 
10.31 8.50 7.40
10.34 8.53 7.81
8.22 8.62 7.78
10.16 8.53 7.44
10.41 8.38 7.63
10.38 8.57 8.03
10.13 8.66 7.41
8.50 8.60 7.15
10.41 8.63 7.21
8.53 8.53 7.12

addTableTexTags.sh

#!/bin/bash

sed -e "s@[[:space:]]@\t\&\t@g" -e "s@[[:space:]]*&*[[:space:]]*\$@\t \\  \\\\n@g" 
 // Tried Escaping "\\" with "/" here and there 
 // but cannot get a line ending with "\\ \n".
