Tables
Rows start/end with "|" for normal rows; "^" for headers.
Define rowspan (vertically connected cells) with ":::".
Define colspan(empty cells) with double pipe "||". 
^Heading 1   ^ Heading 2    ^ Heading 3   ^
|Row 1 Col 1 | Row 1 Col 2  | Row 1 Col 3 |
|Row 2 Col 1 | colspan (note double pipe) ||
|Row 3 Col 1 | Row 2 Col 2  | Row 2 Col 3 |
|:::         | Row 3 Col 2  | Row 3 Col 3 |
Align cells by adding at least two whitespaces at
the opposite end of text. Two spaces on the left
to align right. Two spaces on the right to align left.
Two spaces at both ends to center.
Vertical Headers
|          ^ Heading 1     ^ Heading 2    ^
^Heading 3 | Row 1 Col 2   | Row 1 Col 3  |
^Heading 4 | no colspan    |              |

Basic Macros
No Table of Contents1~~NOTOC~~
No Webpage Caching2~~NOCACHE~~

1 If this macro is found on the page, no table of contents will be created
2 DokuWiki caches all output by default. Sometimes this might not be wanted
(eg. when the syntax above is used), adding this macro will force
DokuWiki to rerender a page on every call.
