CSV 2 Table formatter:Wikka

CSV 2 Table formatter

Features

Rows of the table alternate background color

Column alignment: left, right, center or default

Table headers/footers using wiki style heading markers

Add comments in between data by starting a line with (#); blank lines are ignored

Cells can be surrounded in double quotes (")

It is possible to escape semi-colons with a backslash (\), that should appear in text

Camel links in cell text are linked to their wiki internal pages

Text in quotes is preserved e.g., whitespace, no splitting on semi-colons

History

2005-05-09 Published on main site - OnegWR

Sept-2019 Code clean-up, remove deprecated code, more features, fix bugs - ThePLG

Mar-2020 Upgrade code for PHP7, add some CSS formatting options.

TODO

camel links are really hard to see

Add more cell formatting options: text/background color, alignment, bold, italic, ...

Find a way to implement a "\n" in a cell (every call to $this->Format() is another include of formatters/wakka.php, so I would like to find another way...)

Use more CSS classes
