slate-edit-table


A Slate plugin to handle table edition.

Demo: gitbookio.github.io/slate-edit-table/

Install

``
npm install slate-edit-table
`

Features

* Pressing Up/Down moves the cursor to the row above/below
* Pressing Enter inserts a new row
* Pressing Cmd+Enter (Ctrl+Enter on Windows/Linux) exits the table, into a new default block
* Pressing Tab moves the cursor to next cell
* Pressing Shift+Tab moves the cursor to previous cell

All these default features are configurable.

$3

Here are how different cases of copy-paste are handled by the plugin:

1. Copying the content of a single cell into another cell → The content of the first cell is pasted inside the second cell
2. Copying the content of a single cell outside the table → Just the content of the cell is pasted (not the table)
3. Copying some content into a cell → The content is inserted inside the cell
4. Copying multiple cells somewhere else inside the table → The copied fragment of table is patched at the given position, overwritting cells and adding rows and columns if necessary.
5. Copying multiple cells outside the table → A new table is pasted, containing the copied cells.

Simple Usage

`js
import EditTable from 'slate-edit-table';

const tablePlugin = EditTable(/ options /);

const plugins = [tablePlugin];
`

Data structure

Here is what your Slate document containing tables should look like:

`jsx


Some text

Any block can goes into cells

Second row

Second row




`

Options

Option object you can pass to the plugin.

* [typeTable: string] — type for table
* [typeRow: string] — type for the rows.
* [typeCell: string] — type for the cells.
* [typeContent: string] — default type for blocks in cells. Also used as default type for blocks created when exiting the table with Mod+Enter.

EditTable

$3

Constructs an instance of the table plugin, for the given options. You can then add this instance to the list of plugins passed to Slate.

Once you have constructed an instance of the plugin, you get access to utilities and changes through pluginInstance.utils and pluginInstance.changes.

TablePosition

An instance of TablePosition represents a position within a table (row and column).
You can get your current position in a table by using plugin.utils.getPosition(value).

#### position.getWidth() => number

Returns the number of columns in the current table.

#### position.getHeight() => number

Returns the number of rows in the current table.

#### position.getRowIndex() => number

Returns the index of the current row in the table.

#### position.getColumnIndex() => number

Return the index of the current column in the table.

#### position.isFirstCell() => boolean

True if on first row and first column of the table

#### position.isLastCell() => boolean

True if on last row and last column of the table

#### position.isFirstRow() => boolean

True if on first row

#### position.isLastRow() => boolean

True if on last row

#### position.isFirstColumn() => boolean

True if on first column

#### position.isLastColumn() => boolean`

True if on last column
