Column settings

GridViewTable(
    settings=GridViewTableSettings(
        columns=True,
        order=True,
        visibility=True,
        pinning=True,
        sizing=True,
        presets=True,
    ),
)

When settings is set, the table renderer shows the gear control and column settings modal.

Features

Feature	Behavior
Drag reorder	SortableJS (host base template CDN)
Show/hide	Per column or column group
Pin L/R	Standalone columns
Named presets	GridPreference.col_presets
Session state	localStorage per grid_id

Simple table and AG-Grid share the same modal (GridView.createColumnSettings).

The renderer owns gear placement. GridViewButtonAction has no built-in action="table_settings" handler; use GridViewTable.settings and the rendered control rather than declaring a non-functional action.

Persistence layers

Layer	Storage
Session	localStorage — column layout, filters, quick search
Named presets	GridPreference via POST api_grid_preferences
