There is a lot of space on the left and below the line with columns. There are other way to show this?

awk -v numlines=$( wc -l t | awk '{print $1}' ) '{ if (NF>0) { for (i=1;i<=5;i++) printf("%-20s ",$i) ; if (NR != numlines) { print "" } } }' inputfile

The 'numlines=$(' portion puts the number of lines in the input file into a variable available to awk called numlines. 'NF>0' ensures blank lines are ignored. 'printf(%-20s' ensures the fields are left justified and 20 characters wide. The 'NR != numlines' prints a line feed except at the end of the file.
