G'day sidsinha,

The data you present is at odds with what you've described. The following works on the data you've shown: 

$ perl -Mstrict -Mwarnings -le '
    my @wtodays=
    q{cOne cTwo   cThree 13 sec  cFour
    cOne cTwo   cThree 11 sec  cFour
    cOne cTwo   cThree 1 min 2 sec  cFour
    cOne cTwo   cThree 13 sec  cFour};

    my $re = qr{
        ^                                   # anchor: start of line
        \s*                                 # discard: possible whites
+pace
        (\w+)                               # capture: cOne
        \s+                                 # discard: whitespace
        (\w+)                               # capture: cTwo
        \s+                                 # discard: whitespace
        \w+                                 # discard: cThree
        \s+                                 # discard: whitespace
        ((?:\d+ \s+ min \s+)? \d+ \s+ sec)  # capture: possible min an
+d sec

    for (@wtodays) {
        while (/$re/g) {
            push @table_data => [$1, $2, $3, $4];
        }
    }

    {
        local $" = "|";

        for (@table_data) {
            print "@$_";
        }
