Interface Yiisoft\Yii\DataView\GridView\Column\ColumnRendererInterface

Interface for column renderers that handle the visual presentation of grid columns.

Column renderers are responsible for transforming column definitions into HTML output by configuring cells for different parts of the column (container, header, body, footer). Each renderer works with a specific column type and handles its unique rendering requirements.

Features:

• Column container configuration
• Header cell rendering with optional visibility
• Data cell rendering with row context
• Footer cell rendering
• Context-aware rendering decisions

Example implementation: `php class CustomColumnRenderer implements ColumnRendererInterface {

public function renderColumn(ColumnInterface $column, Cell $cell, GlobalContext $context): Cell
{
    return $cell->addClass('custom-column');
}

public function renderHeader(ColumnInterface $column, Cell $cell, HeaderContext $context): ?Cell
{
    return $cell->content('Custom Header');
}

public function renderBody(ColumnInterface $column, Cell $cell, DataContext $context): Cell
{
    return $cell->content($context->data['value']);
}

public function renderFooter(ColumnInterface $column, Cell $cell, GlobalContext $context): Cell
{
    return $cell->content('Total');
}

} `
