!!! Rows versus Columns
I think there are two ways, column and row orientation. Most wikis are row oriented. For some tasks rows are better, for some tasks columns are better. I'm astonished that not more wikis implement column based tables (perhaps because HTML, LaTeX are row oriented).

{{{
>> Header1
> column1, row1
> column1, row2
> column1, row3
>> Header2
> column2, row1
> column2, row2
> column2, row3
}}}

This is easy to cut and paste, doesn't interfere with long lines, line breaks or markup. It's easy to add rows and easy to add columns. Hard thing is to find the right row when there are lots of rows and few columns (row orientation might be better then). Harder to implement than row orientation, because HTML is row
oriented. Multi row is easy

{{{
>,> rowspan 2
}}}

but column span is more difficult. Could be done with an empty line

!![PukiWiki]

There are two ways for describing Tables.

!use "|" as delimiter
Example:
{{{
| row1-column1 | row1-columun2 |
| row2-column1 | row2-columun2 |
}}}

There are some commands to control table of elements.
"LEFT: CENTER: RIGHT: BGCOLOR(color): COLOR(color): SIZE(num): "

Example:
{{{
|LEFT:row1-column1 |RIGHT:row1-columun2 |
}}}

* You can control the formats of line with character "c" at the end. The commands to control elements are the same as avobe.
* You can make the line as header line (thead) with character "h" at the end.
* You can make the line as footer line (tfoot) with character "f" at the end.
* You can make the elements as a header (th) with character "~" in front of an element.
* Single element ">" means column-span, unite it to the right cell.
* Single element "~" means row-span, unite it to the upper cell.



!use CSV format
Example:
{{{
,row1-column1,row1-columun2,
,row2-column1,row2-columun2,
}}}

You can also write elements with double-quotation(").
{{{
,"row1-column1","row1-columun2",
,"row2-column1","row2-columun2",
}}}

* Single element "==" means column-span, unite it to the right cell.
* You can move the side of the elements with a space insert at the side.
Left side:
{{{
,left ,
}}}
Centering:
{{{
, center ,
}}}
Right side:
{{{
, right,

!Simple tables:

||1      ||2      ||3      ||
}}}

Whitespace controls alignment (left, center, right).
Empty cells are fused.

!Complex tables:

{{{
<table pos/r, country/l, oda/r>
pos=Rank
country=Country
oda=%GNP
pos=1
country=Norway
oda=0.92
pos=2
country=Denmark
oda=0.84
pos=3
country=Netherlands
oda=0.81
pos/c=...
pos=9

oda=0.38
pos/c=...
pos=22
country=United States
oda/mark/r=0.14
----
}}}

Columns are labelled, cells are created by assigning to labels. Cells can contain multiple paragraphs, lists, etc. CSS classes can be added per table, per column, or per cell. Missing cells are fused with neighbours.

!![PBwiki]

* Table rows can be made by beginning and ending a line with <raw>|</raw> (vertical bar). The content of the row is placed between the bars. If more than one cell is desired for any particular row, an additional <raw>|</raw> is used as the separator.
* Adjacent table rows will be automagically combined into a single table.
