How to add pagination to svelte-table?

Svelte-table doesn't include pagination by default. You need to implement it manually by slicing the rows array based on page state and updating the rows prop, or use external pagination libraries alongside the component.

Svelte-table vs TanStack Table for Svelte?

Svelte-table is a full component with built-in UI and features like sorting/filtering, ideal for quick setup. TanStack Table is a headless utility offering more flexibility without styling opinions. Choose svelte-table for simplicity, or TanStack for complete UI control.

How to conditionally style rows based on data?

Use the classNameRow prop with a function that returns class strings based on row data or index. For example, the README shows how to create striped tables or highlight rows with specific values using such functions.

Does svelte-table support server-side filtering?

No, it's primarily designed for client-side operations. For server-side filtering, you'd need to handle data fetching externally and update the rows prop, as the component processes data locally.

How to use custom Svelte components for cell rendering?

Set the renderComponent property in the column config to a Svelte component. You can pass props using an object with component and props keys, as detailed in the README's renderComponent section.

What's the performance impact with large datasets?

Performance relies on client-side processing, so very large datasets may slow down due to sorting and filtering. Consider implementing virtualization or pagination manually, as svelte-table lacks built-in optimizations for massive data.

What is svelte-table?

Svelte Table is a flexible and customizable table component built specifically for Svelte applications. It provides essential data table functionality like sorting, filtering, row selection, and expandable rows while maintaining a minimal footprint, making it suitable for projects that need interactive data presentation without heavy dependencies.

Target Audience

Svelte developers building applications that require interactive, data-rich tables with custom styling and behavior, such as dashboards, admin panels, or data exploration interfaces.

Value Proposition

Developers choose Svelte Table for its balance of core features and minimalism, offering extensive customization through props, slots, and functions without unnecessary bloat, and it supports both compiled Svelte projects and runtime use via an IIFE build.

Overview

A svelte table implementation that allows sorting and filtering

Use Cases

Best For

Building Svelte applications that need interactive tables with sorting and filtering capabilities.
Creating data-rich dashboards or admin panels with customizable row expansion and selection.
Implementing tables with complex conditional styling for rows and cells based on data or index.
Developing tables that require custom rendering of cells using Svelte components or HTML.
Projects needing a lightweight table solution without heavy framework dependencies.
Scenarios where runtime integration of a table component is needed via an IIFE build outside a bundled Svelte project.

Not Ideal For

Projects requiring out-of-the-box pagination or infinite scrolling for large datasets
Applications that need built-in server-side data operations like sorting and filtering
Teams looking for pre-styled, theme-ready table components with minimal CSS work
Scenarios where deprecated API usage must be avoided to prevent future breaking changes

Pros & Cons

Pros

Extensive Customization Options

Provides slots for header, row, and expanded content, and allows custom rendering via Svelte components or functions, enabling full control over table structure and behavior as shown in the column config examples.

Minimal Dependency Footprint

Built specifically for Svelte with a focus on minimalism, offering core table features without unnecessary bloat, making it lightweight and suitable for projects avoiding heavy dependencies.

Flexible Client-Side Features

Supports sorting, filtering, row selection, and expansion with custom functions, allowing precise data manipulation entirely on the client-side for interactive applications.

Runtime Integration Support

Includes an IIFE build for use outside bundled Svelte projects, enabling easy drop-in usage in plain HTML/JS environments as demonstrated in the README.

Cons

Deprecated API Patterns

The README warns that certain filterValue and searchValue function signatures are set for deprecation, leading to potential breaking changes and requiring migration efforts for existing implementations.

No Built-in Pagination

Lacks pagination features out-of-the-box, forcing developers to implement it manually, which adds complexity and overhead for handling larger datasets effectively.

Manual Styling Overhead

Offers minimal default styling, necessitating significant CSS work via class name props to achieve a polished UI, as evidenced by the extensive className options without pre-built themes.
