Tableau tables is an enhanced markup for Markdown tables, written as a library to make it easy to add as a plugin to existing Markdown processors.
I created tableau because I use Markdown to write standalone documents, and I needed better support for tabular material:
- Headerless tables
- Multiline headers
- Multiple separate headers
- Headers in columns and rows
- Captions
- Layout uses CSS styles and not inline attributes (making it easier to change the style of a whole document)
- Per cell alignment and CSS classes
- Default attributes, both down columns and across rows
- Table-wide classes
- Row and column span
- Continuation lines
Here are some samples.
