# Column Layouts

> Insert responsive multi-column layouts.

## Quick start

Column extensions are included in `StarterKit` by default; no extra imports are needed.

```tsx theme={"theme":{"light":"github-light","dark":"vesper"}}
import { StarterKit } from '@react-email/editor/extensions';
import { EditorProvider } from '@tiptap/react';

const extensions = [StarterKit];

export function MyEditor() {
  return <EditorProvider extensions={extensions} content={content} />;
}
```

## Inserting columns programmatically

Use the `insertColumns` command to add a column layout.

```tsx theme={"theme":{"light":"github-light","dark":"vesper"}}
// Insert a 2-column layout
editor.chain().focus().insertColumns(2).run();

// Insert a 3-column layout
editor.chain().focus().insertColumns(3).run();

// Insert a 4-column layout
editor.chain().focus().insertColumns(4).run();
```

## Building a toolbar

Here's a complete example with a toolbar for inserting column layouts. It uses the `slotBefore`
prop to position the toolbar above the editor.

```tsx theme={"theme":{"light":"github-light","dark":"vesper"}}
import { StarterKit } from '@react-email/editor/extensions';
import { EditorProvider, useCurrentEditor } from '@tiptap/react';
import { Columns2, Columns3, Columns4 } from 'lucide-react';

const extensions = [StarterKit];

function ToolbarButton({
  label,
  icon,
  onClick,
}: {
  label: string;
  icon?: React.ReactNode;
  onClick: () => void;
}) {
  return (
    <button type="button" onClick={onClick}>
      {icon}
      {label}
    </button>
  );
}

function Toolbar() {
  const { editor } = useCurrentEditor();
  if (!editor) return null;

  return (
    <div style={{ display: 'flex', gap: '8px', marginBottom: '16px' }}>
      <ToolbarButton
        label="2 columns"
        icon={<Columns2 size={16} />}
        onClick={() => editor.chain().focus().insertColumns(2).run()}
      />
      <ToolbarButton
        label="3 columns"
        icon={<Columns3 size={16} />}
        onClick={() => editor.chain().focus().insertColumns(3).run()}
      />
      <ToolbarButton
        label="4 columns"
        icon={<Columns4 size={16} />}
        onClick={() => editor.chain().focus().insertColumns(4).run()}
      />
    </div>
  );
}

export function MyEditor() {
  return (
    <EditorProvider
      extensions={extensions}
      content={content}
      slotBefore={<Toolbar />}
    />
  );
}
```

<Tip>
  Use `slotBefore` to render custom UI above the editor, and `useCurrentEditor()` to access
  the editor instance from child components.
</Tip>

## Column spacing

Column layouts render as email-safe tables. Space between columns is stored as the
`cellspacing` attribute on the column layout and exported as the `cellSpacing`
prop on the underlying `Row`.

Select a 2, 3, or 4 column layout in the editor and use **Column spacing** in
the inspector to adjust the gap between columns.

<Tip>
  Column spacing controls the gap between columns. Padding on an individual
  column controls the space inside that column.
</Tip>

## Slash commands

The default slash commands include column layouts. Type `/` and search for "columns":

* **Two Columns**: `TWO_COLUMNS`
* **Three Columns**: `THREE_COLUMNS`
* **Four Columns**: `FOUR_COLUMNS`

See [Slash Commands](/editor/features/slash-commands) for setup details.
