# MultiMarkdown table tools
[](https://www.npmjs.com/package/@felisdiligens/md-table-tools)
> Screenshot of [web demo](https://felisdiligens.github.io/md-table-tools/demo/)
## Features
- Parsing MultiMarkdown, GitHub-flavored Markdown, HTML, DokuWiki, or CSV tables into intermediary
- Converting intermediary back to MultiMarkdown, GitHub-flavored Markdown, HTML, DokuWiki, or CSV tables
- Formatting or minifying MultiMarkdown or GFM tables
- Manipulating parsed/intermediary tables (⚠️ *possibly buggy, please run `Table.update()` after making any changes*), e.g.
- by adding, deleting, or moving rows/columns
- by changing the content of table cells
- by merging or splitting table cells
- by changing the text alignment within a column
- etc.
## Module
This project gets packaged as CommonJS and ES module. Types are generated as well.
To install, run
```bash
npm i @felisdiligens/md-table-tools
```
## Usage / Examples
### Web demo
A web demo (see screenshot above) can be accessed [here](https://felisdiligens.github.io/md-table-tools/demo/).
The source code is under `./demo`.
### CLI demo
```bash
$ npm run demo
```
```typescript
import { MultiMarkdownTableParser } from "@felisdiligens/md-table-tools";
import { HTMLTableRenderer } from "@felisdiligens/md-table-tools";
const mdParser = new MultiMarkdownTableParser();
const htmlRenderer = new HTMLTableRenderer();
var mdTable = `
| Example | table |
|---------|--------|
| Hello | world! |
`;
// Parse markdown to intermediary:
var intermediaryTable = mdParser.parse(mdTable);
// Make some changes:
intermediaryTable.getCell(1, 1).setText("everyone!");
intermediaryTable.update();
// Render as HTML:
var htmlTable = htmlRenderer.render(intermediaryTable);
/* Output:
| Example |
table |
| Hello |
everyone! | <--- Changed!
*/
```
### Projects
See [my Joplin plugin](https://github.com/FelisDiligens/joplin-plugin-multimd-table-tools) as an example for usage.

You can access the documentation here: [./docs/modules.md](/docs/modules.md).
Or click on one of the classes below:
- All classes implementing the interface [`TableRenderer`](/docs/interfaces/TableRenderer.md):
You can always use the `TableRenderer.render(Table)` method to get a rendered string.

- [`DokuWikiTableRenderer`](/docs/classes/DokuWikiTableRenderer.md)
- All classes implementing the interface [`TableParser`](/docs/interfaces/TableParser.md):
You can always use the `TableParser.parse(string)` method to get an intermediary `Table` object.

- [`DokuWikiTableParser`](/docs/classes/DokuWikiTableParser.md)
- Intermediary classes:
You can access rows, columns, cells, and the caption from the `Table` parent class.
Use these to manipulate the table. Don't forget to run `Table.update()` method afterwards!

## MultiMarkdown Syntax
This module mostly follows the MultiMarkdown specs: https://fletcher.github.io/MultiMarkdown-6/syntax/tables.html
With a few exceptions:
- You can merge cells vertically by writing `^^` into a cell.
- You can use `\` to join rows together.
### Differences to tables in GitHub-flavored Markdown (and similar variants)
GitHub-flavored Markdown tables (and similar variants) are fully supported, with these additional features:
- You can merge cells horizontally by adding additional pipes (`|`) at the end of the cell.
- You can merge cells vertically by writing `^^` into a cell.
- You can merge the row below by writing `\` at the end of a row.
- You can add a caption above or below to the table. Captions can optionally have labels.
- You can have a header with multiple rows.
- You can omit the header.
- You can divide the table into multiple sections by adding a single empty line in-between rows.
### Differences to tables in DokuWiki
- You can use `^^` instead of `:::` to merge cells vertically.
- You can merge the row below by writing `\` at the end of a row.
- You can add a caption above or below to the table. Captions can optionally have labels.
- You can divide the table into multiple sections by adding a single empty line in-between rows.
- You **cannot** mix header cells (``) and ordinary cells (` | `) in a single row.
- You **cannot** independently align cells (only the whole column).
