# `MishkaGervaz.Table.Behaviours.ColumnType`
[🔗](https://github.com/mishka-group/mishka_gervaz/blob/v0.0.1-alpha.3/lib/mishka_gervaz/table/behaviours/column_type.ex#L1)

Behaviour for column type renderers.

Implement this behaviour to create custom column types that render
values in specific ways (badges, links, colors, etc.).

## Example

    defmodule MyApp.ColumnTypes.Color do
      @behaviour MishkaGervaz.Table.Behaviours.ColumnType
      use Phoenix.Component

      @impl true
      def render(value, _column, _record, _ui) do
        assigns = %{value: value}

        ~H"""
        <div class="w-6 h-6 rounded" style={"background: #{@value}"}></div>
        """
      end
    end

Then use in DSL:

    column :background_color, type: MyApp.ColumnTypes.Color

See `MishkaGervaz.Table.Types.Column` (registry),
`MishkaGervaz.Table.Entities.Column`, and
`MishkaGervaz.Table.Behaviours.TypeRegistry`.

# `cell_class`
*optional* 

```elixir
@callback cell_class(column :: map()) :: String.t() | nil
```

Optional: Return CSS class for the cell.

# `render`

```elixir
@callback render(
  value :: any(),
  column :: map(),
  record :: map(),
  ui :: module()
) :: Phoenix.LiveView.Rendered.t()
```

Render the column cell value.

## Parameters

- `value` - The value to render (extracted from record based on column source)
- `column` - Column configuration map from DSL
- `record` - The full record (for accessing other fields if needed)
- `ui` - UI adapter module for consistent styling

## Returns

Phoenix.LiveView.Rendered.t()
