NAME HTML::QuickTable - Quickly create fairly complex HTML tables SYNOPSIS use HTML::QuickTable; my $qt = HTML::QuickTable->new( font_face => 'arial', table_width => '95%', labels => 1 ); my $table1 = $qt->render(\@array_of_data); my $table2 = $qt->render(\%hash_of_keys_and_values); my $table2 = $qt->render($object_with_param_method); DESCRIPTION This modules lets you easily create HTML tables. Like CGI::FormBuilder, this module does a lot of thinking for you. For a comprehensive module that gives you the ability to tweak every aspect of table building, see HTML::Table or CGI.pm. This one gives you a lot of control, but is really designed as an easy way to expand arbitrary data structures. The simplest table can be created with nothing more than: my $qt = HTML::QuickTable->new; print $qt->render(\@data); Where "@data" would be an array holding your data structure. For example, the data structure: @data = ( [ 'nwiger', 'Nathan Wiger', 'x43264', 'nate@wiger.org' ], [ 'jbobson', 'Jim Bobson', 'x92811', 'jim@bobson.com' ] ); Would be rendered as something like:
nwigerNathan Wigerx43264nate@wiger.org
jbobsonJim Bobsonx92811jim@bobson.com
Of course, the best use for this module is on dynamic data, say something like this: use DBI; use HTML::QuickTable; my $qt = HTML::QuickTable->new(header => 1); # print header my $dbh = DBI->connect( ... ); my $all_arrayref = $dbh->selectall_arrayref("select * from billing"); print $qt->render($all_arrayref); With "header => 1", you will get a brief "CGI" header as well as some basic "HTML" to prettify things. As such, the above will print out all the rows that your query selected in an "HTML" table. FUNCTIONS new(opt => val, opt => val) The "new()" function takes a list of options and returns a "$qt" object, which can then be used to "render()" different data. The "new()" function has a flexible options-parsing mechanism that allows you to specify settings to pretty much any element of the table. Options include: header => 1 | 0 If set to "1", a basic "CGI" header and leading "HTML" is printed out. Useful if you're really looking for quick and dirty. Defaults to "0". htmlize => 1 | 0 If set to 1, then all values will be run through a simple filter that creates links for things that look like email addresses or websites. Also, "*word*" will be changed to "word", and "_word_" will be changed to "word". labels => 1 | 0 | LTRB If set to 1, then the first row of the data is used as the labels of the data columns, and is placed in "" tags. For example, if we assume our above data structure, and said: my $qt = HTML::QuickTable->new(... labels => 1); unshift @data, ['User', 'Name', 'Ext', 'Email']; print $qt->render(\@data); You would get something like this:
UserNameExtEmail
nwigerNathan Wigerx43264nate@wiger.org
jbobsonJim Bobsonx92811jim@bobson.com
Since the labels are placed in "" tags, you can then use the extra "HTML" options described below to alter the way that the labels look. You can also now set this to a string that includes the characters L, T, R, and B, to specify that "" tags should be created for the Left, Top, Right, and Bottom rows and columns. So for example: labels => 'LT' Would alter the table so that both the first row AND first column had "" instead of "" elements. This is useful for creating tables that have two axes, such as calendars. null => $string If set, then null (undef) fields will be set to that string instead. This is useful if pulling a bunch of records out of a database and not wanting to get blank table spaces everywhere there's a null field. For example: my $qt = HTML::QuickTable->new(null => '-'); my $all_arrayref = $sth->fetchall_arrayref; print $qt->render($all_arrayref); By default null table elements are left blank. nulltags => \%hash In addition to just changing the string used to represent null data, you may want to change the look of it as well. These tags will become attributes to the "" element holding the null field. So, settings like this: null => 'N/A', nulltags => {bgcolor => 'gray'}, Would result in an element like the following for null fields: N/A Make sense? title => $string If you set "header => 1", then you can also specify the "title" to be prefixed to the document. Otherwise this option is ignored. vertical => 1 | 0 If you set this to 1, then it fundamentally changes the way in which data is expanded. Instead of walking the data structure and building rows horizontally, each element of data will become a column. This will be described more below under "render()". text => 'string' Just like FormBuilder, this text is printed out for you to easily annotate your table. body => {opt => val, opt => val} font => {opt => val, opt => val} table => {opt => val, opt => val} td => {opt => val, opt => val} th => {opt => val, opt => val} tr => {opt => val, opt => val} These options can be used to set attributes to be used on the applicable tag. For example, if you wanted the table width to be "95%" and the "border" to be "1", you would say: my $qt = HTML::QuickTable->new(table => {width => '95%', border => 1}); Of course, you can specify as many different options as you want: my $qt = HTML::QuickTable->new(table => {width => '95%', border => 1}, td => {class => 'td_el'}, font => {face => 'arial,helvetica'} ); As an alternative form, keep reading: body_opt => val font_opt => val table_opt => val td_opt => val th_opt => val tr_opt => val Instead of having to specify a hashref, you can use this option form to specify "HTML" tags. For example, if you want to set the font face, either of these will do the exact same thing: my $qt = HTML::QuickTable->new(font => {face => 'verdana'}); my $qt = HTML::QuickTable->new(font_face => 'verdana'); Again, you can specify any "HTML" tag you want and it will get included. Anything after the underscore is taken as the tag name and placed into the output "HTML" verbatim. render(\@data | \%data | $object) The "render()" function can accept either an "arrayref", "hashref", or "object". It then recursively expands the data per the options you specified to "new()". Each data structure is rendered differently: arrayref (\@array) An "arrayref" should expand intuitively; each row in the array becomes another row in the table. If you specify the "labels" option, then the first row is taken as the column labels and is placed within "" elements. object ($object) An "object" also expands quite simply. First, the "object"'s "param()" method is called to get a list of keys. Then, for each key the value is placed in the array. The key is taken as the label for that column, and is placed within a "". As an example, you can dump a nice table of your "CGI" query with: use CGI; use HTML::QuickTable; my $cgi = CGI->new; my $qt = HTML::QuickTable->new(header => 1); print $qt->render($cgi); hashref (\%hash) A "hashref" is first sorted by "key". Then, each data element becomes a data element for that column. For example: %user = ( 'nwiger' => ['Nathan Wiger', 'nate@wiger.org'], 'jbobson' => ['Jim Bobson', 'jim@bobson.com'] ); print $qt->render(\%user); Would be rendered as:
jbobsonJim Bobsonjim@bobson.com
nwigerNathan Wigernate@wiger.org
Note that it's very similar to the way arrays are handled. The benefit here is that this allows you to expand arbitrary data structures. If it's a "hashref" of "hashrefs", for example: %user = ( 'nwiger' => { name => 'Nathan Wiger', email => 'nate@wiger.org' }, 'jbobson' => { name => 'Jim Bobson', email => 'jim@bobson.com'} ); print $qt->render(\%user); Then some Major Magic (tm) happens and you'll get something like this:
emailname
jbobsonjim@bobson.comJim Bobson
nwigernate@wiger.orgNathan Wiger
Notice that the keys were sorted alphabetically and output in order. Also, note that the "key" is not labeled in the "". To remedy this, you must specify the "keylabel" option to "new()": my $qt = HTML::QuickTable->new(keylabel => 'user'); # ... print $qt->render(\%user); That would create the same "HTML" as above, except the first column label would be "user". NOTES The 'B' option to 'labels' is currently broken, due to the fact that "render()" recursively calls itself and thus loses track of where it is. But who the heck puts labels at the *bottom* of an HTML table?? If you run into a bug, please DO NOT submit it via "rt.cpan.org", it causes me alot of extra work.
