in thread Help with Creating a Table from array ref I parsed in

I've used formats

<crocodile_dundee>That's not a format. This is a format!</crocodile_dundee>

#!/usr/bin/env perl
use strict;
use warnings;

my @fields;

format STDOUT =
@<<<<<<<<<<  @####.###### @####.###### @<<<<<<
@fields
.

while (my $line = <DATA>) {
    chomp $line;
    @fields = split /\s+/, $line, 4;
    unshift @fields, ' ' if 4 > @fields;
    write;
}

    Thank you all! These sample codes really help me to think about how to manipulate arrays to create new formats.

    Hi TIMTOWTDI,

    I am a little lost trying to figure out how your script works.

    I read Perl #sprintf FORMAT, LIST and could not understand how your "format STDOUT" works. Can you explain it? The Perldocs I read do not have the format you presented here for your script

    Say, if I were to "left-justify" each column, how can I add the "-" to your "format STDOUT" statement and be left-justified? Also, how to manipulate the spacing in between columns?

    I's like the table to look like this below, perhaps, I can understand your format statement works if I see it...maybe?

    This is your code below with the edit to allow a longer string for the 1st column

    #!/usr/bin/env perl
use strict;
use warnings;

my @fields;

# For the longer 1st Column name, I added some more spaces so it won't
+ concat the name. NOt sure how the left-justify can be done with this
+ format STDOUT statement? 
format STDOUT =
@<<<<<<<<<<<<  -@#####.###### @####.###### @<<<<<<
@fields
.

while (my $line = <DATA>) {
    chomp $line;
    @fields = split /\s+/, $line, 4;
    unshift @fields, ' ' if 4 > @fields;
    write;
}

# All four columns should be left-justified and should line up whether
+ it is a positive or negative number.

      Hi TIMTOWTDI

      Hi perlynewby. TIMTOWTDI is an abbreviation: in this context it was there to highlight that the method I showed was different to that from kcott. I'm hippo.

      I read Perl #sprintf FORMAT, LIST and could not understand how your "format STDOUT" works. Can you explain it? The Perldocs I read do not have the format you presented here for your script

      You have been reading different docs. Please see the docs for format which I linked to previously and which are entirely unrelated to sprintf. Hopefully they will make it all clear. Give it a try once you have read through those and if you are still stuck please ask further.

      🦛

      Here is an earlier reply I did using format with aligned columns using sprintf: https://www.perlmonks.org/?node_id=11136290

      sample output from that thread:
