Svelte Advanced DataTable

A configurable, server-aware data table for Svelte 5 with first-class support for DaisyUI.

Features

• Server-side or client-side data — FetchApiDataSource, ApiFunctionDataSource, SvelteQueryDataSource, or LocalDataSource (client-side filter, sort, paginate).
• Pagination with configurable page size and an items-per-page selector.
• Sorting — click to sort, Shift-click for multi-column sort.
• Search and filtering — basic text search or a structured query parser with field aliases.
• Row selection and actions — single + multi-select with a bulk action toolbar, per-row dropdown, primary/destructive variants, two-way bind:selectedIds.
• Settings popover — items per page, density (compact/default/spacious), column visibility, column reordering, reset persisted column widths.
• Column resizing and reordering with persisted widths and order.
• Sticky header that pins while the body scrolls.
• Export — CSV / JSON popover with delimiter, quoting and line-ending options. Use buildExportUrl to delegate large exports to the server.
• State persistence — separate session and persistent tiers (sessionStorage / localStorage / custom backend) for page, sort, search, column order, widths, density and items-per-page.
• Internationalisation — built-in message config, svelte-i18n, or a custom MessageFormatter.
• Error handling — onError callback plus a customisable errorState slot.
• Custom column components for fully bespoke cell rendering.

Installation

# Install Tailwind CSS and DaisyUI first (see https://daisyui.com/docs/install)

pnpm add svelte-advanced-datatable

Basic usage

<script lang="ts">
    import type { DataTableConfig } from 'svelte-advanced-datatable';
    import { ComponentType, FetchApiDataSource } from 'svelte-advanced-datatable';
    import { DataTable } from 'svelte-advanced-datatable/daisyUi';

    interface UserData {
        id: number;
        userName: string;
    }

    const config: DataTableConfig<UserData> = {
        type: 'userData',
        columnProperties: {
            id: { type: ComponentType.NUMBER },
            userName: { type: ComponentType.STRING }
        },
        dataUniquePropertyKey: 'id',
        messageConfig: {
            id: { label: 'Id' },
            userName: { label: 'Username' }
        }
    };

    const dataSource = new FetchApiDataSource<UserData>('/api/users/list');
</script>

<DataTable {config} {dataSource} />

Selection + actions

Register actions to automatically get a checkbox column, a per-row dropdown and a bulk toolbar:

<script lang="ts">
    import type { SelectionId } from 'svelte-advanced-datatable';

    let selectedIds: SelectionId[] = $state([]);

    const config: DataTableConfig<UserData> = {
        // ...other options
        actions: [
            { key: 'edit', onSingle: (user) => editUser(user) },
            { key: 'archive', primary: true, onMulti: (ids) => archive(ids) },
            { key: 'delete', variant: 'destructive', primary: true, onMulti: (ids) => remove(ids) }
        ]
    };
</script>

<DataTable {config} {dataSource} bind:selectedIds />
