Extensions¶

All 15 DataTables v2 extensions are bundled — there is nothing extra to install. Each activates through its Options helper (which sets the DataTables option the extension reads).

from dt2 import Options, dt2

opts = (Options(df)
        .buttons(["copyHtml5", "csvHtml5", "excelHtml5", "print"])
        .select({"style": "os"})
        .responsive()
        .fixed_header()
        .row_group("field"))

dt2(df, options=opts)

dt2.extensions() returns the bundled list and versions.

Activation helpers¶

Helper	DataTables option	Extension
`buttons(ids, target=None)`	`buttons` (+ layout)	Buttons
`select(cfg=True)`	`select`	Select
`responsive(cfg=True)`	`responsive`	Responsive
`fixed_header(cfg=True)`	`fixedHeader`	FixedHeader
`fixed_columns(cfg)`	`fixedColumns`	FixedColumns
`key_table(cfg=True)`	`keys`	KeyTable
`scroller(scroll_y, cfg=True)`	`scroller` (+ `scrollY`)	Scroller
`row_group(data_src)`	`rowGroup`	RowGroup
`row_reorder(cfg=True)`	`rowReorder`	RowReorder
`col_reorder(cfg=True)`	`colReorder`	ColReorder
`search_panes(cfg=True)`	`searchPanes`	SearchPanes
`search_builder(cfg=True)`	`searchBuilder`	SearchBuilder
`state_restore(cfg=True)`	`stateRestore` (+ `stateSave`)	StateRestore
`column_control(cfg=True)`	`columnControl`	ColumnControl

(DateTime is bundled as a dependency of SearchBuilder.)

Buttons & export¶

Options(df).buttons(["copyHtml5", "csvHtml5", "excelHtml5", "print"])

Copy / CSV / Excel / Print work out of the box (jszip is bundled).
PDF export (pdfHtml5) needs pdfmake, which is not bundled (it is ~1 MB) — a deferred optional extra.
Buttons are placed in the layout automatically. To relocate them into your own container, pass target="#my-toolbar".

For the simpler layout-based variant (button ids + a CSS class in a chosen layout slot), use use_buttons(...).
