Tables may be authored in wiki pages using either HTML table elements directly, or using wikicode formatting to define the table. HTML table elements and their use are well described on various web pages and will not be discussed here. The benefit of wikicode is that the table is constructed of character symbols which tend to make it easier to perceive the table structure in the article editing view compared to HTML table elements.
A good general rule of thumb is to avoid using a table unless you need to. Table markup often complicates page editing.
table caption,optional; only one per table and between table start and first row
|-
table row,optional on first row -- wiki engine assumes the first row
!
table header cell, optional. Consecutive table headers may be added on same line separated by double marks (!!) or start on new lines, each with its own single mark (!).
|
table data cell, required! Consecutive table data cells may be added on same line separated by double marks (||) or start on new lines, each with its own single mark (|).
|}
end table
The above marks must start on a new line except the double || and !! for optionally adding consecutive cells to a line.
XHTML attributes. Each mark, except table end, optionally accepts one or more XHTML attributes. Attributes must be on the same line as the mark. Separate attributes from each other with a single space.
Cells and caption (| or ||, ! or !!, and |+) hold content. So separate any attributes from content with a single pipe (|). Cell content may follow on same line or on following lines.
Table and row marks ({| and |-) do not directly hold content. Do not add pipe (|) after their optional attributes. If you erroneously add a pipe after attributes for the table mark or row mark the parser will delete it and your final attribute if it was touching the erroneous pipe!
Content may (a) follow its cell mark on the same line after any optional XHTML attributes or (b) on lines below the cell mark. Content that uses wiki markup that itself needs to start on a new line, such as lists, headers, or nested tables, must of course be on its own new line.
Simple table
Plain
The following table lacks borders and good spacing but shows the simplest wiki markup table structure
For more table-ish looking wiki markup cells can be listed on one line separated by ||. This does not scale well for longer cell content such as paragraphs. It works well for short bits of content however, such as our example table.
Extra spaces within cells in the wiki markup can be added, as I have done in the wiki markup below, to make the wiki markup itself look better but they do not affect the actual table rendering.
HTML attributes can be added to tables on this page but have been left out of the following example for simplicity.
Orange
Apple
more
Bread
Pie
more
Butter
Ice cream
and more
{|
| Orange || Apple || more
|-
| Bread || Pie || more
|-
| Butter || Ice cream || and more
|}
With HTML attributes
You can add HTML attributes to make your table look better
HTML H1, H2, H3, H4 etc. headings can be created the standard wiki markup way with ==equal== signs and must be on a line all by themselves to work.
Preview the whole table. If you click on an edit tab for a heading within a table, edit, and preview, the parent table will display erroneously broken because part of it will be missing.
Keep the heading hierarchy consistent with the rest of the page so that the table of contents at page top works correctly.
