List table

Allow users to easily scan and quickly access key data organized in logical, hierarchical patterns

This is a Lab component!

That means it doesn't satisfy our definition of done and may be changed or even deleted. For an exact status, please reach out to the Fancy team through the dev_fancy or ux_fancy channels.

import { ListTable } from "@siteimprove/fancylab";

#Examples

Composition:

Background: A subtle background color can visually separate the list table from surrounding content. Use a neutral color that doesn't compete with the content.
Item Count (Optional): Display the total number of items in the list, especially for filtered or large datasets. Add context when applicable (e.g., "Filtered by: Active").
Sorting Indicator (Optional): Clearly indicate the active sorting criteria (e.g., "Sorted by Name (Ascending)"). This helps users understand how the list is organized.
Rows and Cells (Optional): Rows represent individual data items, while cells hold specific pieces of information within a row.

#Basic usage

Use Cases:

Surface essential information quickly (e.g., site names, scores, policy summaries).
Offer an overview of data, acting as an entry point to more details. (e.g., Core wins).
Enable users to scan for patterns and insights.

Best Practices:

Focus on the most important data points, keeping information density low to avoid overwhelming users.
Consider embedding list tables within cards or other primary content areas to provide context.
Keep additional actions (shortcuts, CTAs) to a maximum of two per row to maintain visual clarity.

Sorted by Dish (ascending)

Some table data in a list
Dish	Calories	Protein
Beef Stir-Fry	450 calories	25 g protein
Grilled Salmon	500 calories	30 g protein
Veggie Lasagne	350 calories	12 g protein

CodeHTML output

Theme: agentic-ai-2025

<ListTable
	items={sortItems(items, { property: "dish", direction: "asc" })}
	columns={[
		{
			header: { content: "Dish" },

	]}
	loading={false}

#Usage with pagination

Use for large datasets. Provide clear controls and indicate the total number of pages. Consider offering options to adjust items per page.

#Usage with load more buttons

Alternative to pagination when space is limited or the total item count is unknown. Ensure the button is visible and provide loading feedback.

#Usage with sorting

Allow users to reorder the list. Use a Select for options and indicate the current sorting state.

When using sorted lists, you must provide the sortSelect and sort properties as well as the colums[].header.property value of sortable columns.

);

Provide a centralized space for actions that apply to the entire table (filtering, bulk actions, customization). Keep it uncluttered and visually distinct.

CodeHTML output

Theme: agentic-ai-2025

type Calories = { id: number; name: string };
const caloriesAmount: Calories[] = [
	{ id: 1, name: "All calories" },
	{ id: 2, name: "Less than 500 calories" },

				},
			]}
			sort={sort}
			loading={false}
			caption="Some table data in a list"
			{...translations}
		/>
	</>
);

#Usage without filter, sort or count header

For simple, static lists where these features aren't needed. Ensure the list is self-explanatory and visually organized. Consider a card header or title for context.

		loadMoreLabel={(count: number) => `Load ${count} more`}
		loadAllLabel="Load all"
		// leave out the "itemsFoundLabel", "sortByLabel" & "sortedByLabel" props to avoid the header
	/>
);

#Loading state

Use a Spinner and/or brief message to indicate data is being fetched.

Best Practices:

Use a Spinner component to indicate the loading state.
Place the loading indicator in the center of the list table area.
Consider adding a brief message explaining the delay.

#No data state

Communicate clearly that no data matches the criteria. Offer suggestions or actions to help the user.

Best Practices:

Use a visually distinct "empty state" design, read more in Empty state.
Provide a clear, concise message explaining why no data is available.
Offer relevant actions, such as "Try a different search" or "Create a new item".
Avoid blaming the user or using negative language.

Consideration:

The noDataState is used to indicate that no data is available for display. An Empty state component with the type "reassure" and default heading is shown, but it can be overridden by another type with custom text. For guidelines please refer to the Empty state component.

To avoid confusion, in cases where the user has resolved the issues, explain why the data cannot be displayed. E.g. "Accessibility issues have been resolved".

#Placement

ListTable is typically used in the following places:

User-generated content listings (e.g., Site, My policy).
Issue catalogs (e.g., Core wins).

#Style

Siteimprove Design System: Adhere to Siteimprove's guidelines for color, typography, and spacing. If you are not using a component from Fancy, match the styling of your ListTable to existing components for visual consistency.
Always use a header when embedding a ListTable within a Card.
Anchor supporting visuals (thumbnails, etc.) along the row's edge for better scalability.
Incorporate bulk actions like checkboxes or a "mark as favorite" starred button (first column).
Labels:
- Avoid long text in expandable containers.
- Prioritize key information over metadata.
- Ensure each cell's content is self-explanatory to eliminate the need for column headers.

#Do not use when

Highly detailed information or complex relationships. Use Table instead.
Primarily numerical data requiring calculations. Use Table instead.
Extremely large datasets. Use Table instead.
Identifying trends. Use Chart instead.

#Accessibility

#For designers

Ensure sufficient contrast, clear focus indicators, and descriptive labels/alt text for visual elements.

#For developers

This component comes with built-in accessibility, no extra work required.

Explore detailed guidelines for this component: Accessibility Specifications

#Writing

Use concise, descriptive labels for cells.
Follow sentence case conventions. Be mindful of localization.
Maintain consistency in decimal usage (e.g., one decimal places). Do not use 1 decimal in one row and 2 in another.
Avoid punctuation within list unless data contains numbers and units. Follow Grammar and mechanics.
