NAME
Term::Table - Format a header and rows into a table
DESCRIPTION
This is used by some failing tests to provide diagnostics about what
has gone wrong. This module is able to generic format rows of data into
tables.
SYNOPSIS
use Term::Table;
my $table = Term::Table->new(
max_width => 80, # defaults to terminal size
pad => 4, # Extra padding between table and max-width (defaults to 4)
allow_overflow => 0, # default is 0, when off an exception will be thrown if the table is too big
collapse => 1, # do not show empty columns
header => ['name', 'age', 'hair color'],
rows => [
['Fred Flinstone', 2000000, 'black'],
['Wilma Flinstone', 1999995, 'red'],
...
],
);
say $_ for $table->render;
This prints a table like this:
+-----------------+---------+------------+
| name | age | hair color |
+-----------------+---------+------------+
| Fred Flinstone | 2000000 | black |
| Wilma Flinstone | 1999995 | red |
| ... | ... | ... |
+-----------------+---------+------------+
INTERFACE
use Term::Table;
my $table = Term::Table->new(...);
OPTIONS
header => [ ... ]
If you want a header specify it here. This takes an arrayref with
each columns heading.
rows => [ [...], [...], ... ]
This should be an arrayref containing an arrayref per row.
collapse => $bool
Use this if you want to hide empty columns, that is any column that
has no data in any row. Having a header for the column will not
effect collapse.
max_width => $num
Set the maximum width of the table, the table may not be this big,
but it will be no bigger. If none is specified it will attempt to
find the width of your terminal and use that, otherwise it falls back
to the terminal width or 80.
pad => $num
Defaults to 4, extra padding for row width calculations. Default is
for legacy support. Set this to 0 to turn padding off.
allow_overflow => $bool
Defaults to 0. If this is off then an exception will be thrown if the
table cannot be made to fit inside the max-width. If this is set to 1
then the table will be rendered anyway, larger than max-width, if it
is not possible to stay within the max-width. In other words this
turns max-width from a hard-limit to a soft recommendation.
sanitize => $bool
This will sanitize all the data in the table such that newlines,
control characters, and all whitespace except for ASCII 20 ' ' are
replaced with escape sequences. This prevents newlines, tabs, and
similar whitespace from disrupting the table.
Note: newlines are marked as '\n', but a newline is also inserted
into the data so that it typically displays in a way that is useful
to humans.
Example:
my $field = "foo\nbar\nbaz\n";
print join "\n" => table(
sanitize => 1,
rows => [
[$field, 'col2' ],
['row2 col1', 'row2 col2']
]
);
Prints:
+-----------------+-----------+
| foo\n | col2 |
| bar\n | |
| baz\n | |
| | |
| row2 col1 | row2 col2 |
+-----------------+-----------+
So it marks the newlines by inserting the escape sequence, but it
also shows the data across as many lines as it would normally
display.
mark_tail => $bool
This will replace the last whitespace character of any trailing
whitespace with its escape sequence. This makes it easier to notice
trailing whitespace when comparing values.
show_header => $bool
Set this to false to hide the header. This defaults to true if the
header is set, false if no header is provided.
auto_columns => $bool
Set this to true to automatically add columns that are not named in
the header. This defaults to false if a header is provided, and
defaults to true when there is no header.
no_collapse => [ $col_num_a, $col_num_b, ... ]
no_collapse => [ $col_name_a, $col_name_b, ... ]
no_collapse => { $col_num_a => 1, $col_num_b => 1, ... }
no_collapse => { $col_name_a => 1, $col_name_b => 1, ... }
Specify (by number and/or name) columns that should not be removed
when empty. The 'name' form only works when a header is specified.
There is currently no protection to insure that names you specify are
actually in the header, invalid names are ignored, patches to fix
this will be happily accepted.
NOTE ON UNICODE/WIDE CHARACTERS
Some unicode characters, such as 婧 (U+5A67) are wider than others.
These will render just fine if you use utf8; as necessary, and
Unicode::GCString is installed, however if the module is not installed
there will be anomalies in the table:
+-----+-----+---+
| a | b | c |
+-----+-----+---+
| 婧 | x | y |
| x | y | z |
| x | 婧 | z |
+-----+-----+---+
