 ### 3.3 Column Configuration — `EasyColumn<T, V>`
 
-`getColumnConfig(String propertyName)` returns a wrapper that provides type-specific formatting. For all other column properties (header, footer, width, alignment, sorting, freezing, visibility, renderer), use `getColumn()` to access the underlying `Grid.Column<T>` directly.
+`getColumn(String propertyName)` returns an `EasyColumn<T, V>` that provides both type-specific formatting and direct access to all standard `Grid.Column` setters for fluent configuration. The underlying `Grid.Column<T>` is also accessible via `EasyColumn.getColumn()` for any configuration not covered by the delegating API.
