05. while ( $TRUE ) {
06. $i = $line.IndexOf([Char] 9)
07. if ( $i -eq -1 ) { break }
08. if ( $TabWidth -gt 0 ) {
09. $pad = " " * ($TabWidth - ($i % $TabWidth))
10. } else {
11. $pad = ""
12. }
13. $line = $line -replace "^([^\t]{$i})\t(.*)$", "`$1$pad`$2"
14. }
15. $line
16. }

$line = $line -replace "^([^\t]{$i})\t(.*)$", "`$1$pad`$2"
