Behavior comparison

Data grid vs Table

Decisive difference

Data grid is a widget that moves focus cell by cell with arrow keys; Table is static content read in document order.

Data gridChoose Data grid if the user edits, selects, or navigates many cells with the keyboard.
TableChoose Table if the data is read and compared without interaction inside the cells.

Decision

Family question

Should people read tabular data, interact cell by cell, or expand a hierarchy?

Nine dimensions

Dimension	Data gridData grid	TableTable
Trigger	Tab enters one managed focus point; directional keys then move among cells.	Reading starts in the caption and headers; embedded controls keep their own normal activation.
Modality	Non-modal composite widget with an internal focus model.	Non-modal document structure, not a composite widget.
Placement	A bounded tabular workspace with persistent headers and a visible active cell.	Inline with its caption and column or row headers aligned to the represented data.
Interactivity	Roving focus, arrow navigation, sorting, selection, and editing are explicit; focus and selection remain distinguishable.	Cells are read in native table structure; any link, button, or sort control is a separate tab stop.
Focus	Use one consistent roving-tabindex or aria-activedescendant strategy, keep the active cell visible, and never put every cell in the page tab sequence.	Focus remains on the activated sort button when rows reorder; reading cells never gain managed widget focus.
Dismissal	The grid is not dismissed; Escape exits cell interaction and restores grid navigation.	A table is document content and is not dismissible.
Accessible role	grid > row > (columnheader \| rowheader \| gridcell)	table > (thead \| tbody) > tr > (th \| td)
Use case	Large tabular data needs efficient keyboard navigation	People compare values across rows and columns
Mobile behavior	Provide a tested touch model or a simpler list/table alternative when dense two-dimensional operation is impractical.	Preserve header relationships and offer a deliberate overflow or alternate layout instead of visually reordering cells.
