TanStack Table Explained: Everything You Need to Know

Introduction

In the world of modern web development, displaying data effectively and efficiently is a common challenge. Whether it's a simple list of users or a complex financial report, tables are essential. While there are many libraries available to handle tables in React, few offer the flexibility, performance, and ease of use that TanStack Table does.

TanStack Table, previously known as React Table, has quickly become the go-to solution for developers needing powerful and customizable table components. TanStack is not only compatible with React but it also supports Angular, Lit, Qwik, Solid, Svelte, Vue, and also Vanilla JavaScript/TypeScript.

In this blog post, we'll dive into what makes TanStack Table stand out, explore its core features, and provide a hands-on example to get you started.

What is TanStack Table?

TanStack Table is a lightweight, highly customizable, and headless UI for building powerful tables & data grids. By "headless," we mean it comes with all the core functionality and logic for table operations without any user interface. This gives us total control over our table's appearance while also taking advantage of the built-in functionality.

Why choose the TanStack table?

Choosing a table library for your project can be confusing as so many options are available online. Here’s why TanStack Table might be the best fit for your next project:

1. Performance

When our dataset is large managing it efficiently becomes crucial as we also have to take performance into account. TanStack uses features like Virtualization and Tree shaking which are methods for optimising performance. It also optimizes rendering to ensure that even if there are tens of thousands of rows the performance is smooth.

Tree shaking is a process of optimising during final javascript bundling, it removes all the dead code or unused code from the bundle.

Virtualization or Windowing is a technique to improve performance by only rendering the items that are currently in view.

2. Adaptability

TanStack table supports headless architecture which allows us to be free from any built-in UI. Its high customizability lets us integrate it with any CSS framework or theme. This flexibility comes in very handy when design changes are required for almost every project.

3. Advanced Feature

TanStack Table supports a wide range of feature lists such as:

• Sorting with customizable sort functions.

• Built-in filters or custom filter logic.

• Hide or unhide any column.

• Built-in pagination logic.

• Group rows by any criteria.

• Dynamic resizing of columns.

• Select rows with checkboxes or other UI elements.

4. Active Community and Support

TanStack Table is actively maintained and is supported by a great community. The documentation is precise and easy to understand.

Key challenges when using TanStack Table

Although TanStack Table offers many advantages, it also has some drawbacks.

• Managing column width according to data length.

• Making the table responsive for all screen sizes.

• Debugging a custom build table using the TanStack table

• Comprehensive documents can make it difficult to find quick answers.

• The learning curve is steep.

Getting Started with TanStack Table

Let's start with a simple example. We'll create a basic table using TanStack Table.

Step 1: Install TanStack Table

First, let's install TanStack Table and its peer dependencies.

npm install @tanstack/react-table

Step 2: Set Up the Table

We'll start by setting up our table component. For this example, we’ll use a simple dataset of users.

import * as React from 'react';
import {
  createColumnHelper,
  flexRender,
  getCoreRowModel,
  useReactTable,
} from '@tanstack/react-table';

export type User = {
  id: number;
  name: string;
  age: number;
  email: string;
  country: string;
  subscription: string;
  wallet_balance: number;
};

export const users: User[] = [
  {
    id: 1,
    name: 'John Doe',
    age: 35,
    email: 'john.doe@example.com',
    country: 'United States',
    subscription: 'Premium',
    wallet_balance: 150.25,
  },
  {
    id: 2,
    name: 'Alice Smith',
    age: 28,
    email: 'alice.smith@example.com',
    country: 'Canada',
    subscription: 'Basic',
    wallet_balance: 50.75,
  }
];

const columnHelper = createColumnHelper<User>();

const columns = [
  columnHelper.accessor('name', {
    header: () => 'Name',
    cell: (info) => info.getValue(),
  }),
  columnHelper.accessor('age', {
    header: () => 'Age',
    cell: (info) => info.getValue(),
  }),
  columnHelper.accessor('email', {
    header: () => 'Email',
    cell: (info) => info.getValue(),
  }),
  columnHelper.accessor('country', {
    header: () => 'Country',
  }),
  columnHelper.accessor('subscription', {
    header: 'Subscription',
  }),
  columnHelper.accessor('wallet_balance', {
    header: 'Wallet balance',
  }),
];

const Table = () => {
  const [data, _setData] = React.useState([...users]);

  const table = useReactTable({
    data,
    columns,
    getCoreRowModel: getCoreRowModel(),
  });

  return (
      <table>
        <thead>
          {table.getHeaderGroups().map((headerGroup) => (
            <tr key={headerGroup.id}>
              {headerGroup.headers.map((header) => (
                <th
                  key={header.id}
                >
                  {header.isPlaceholder
                    ? null
                    : flexRender(
                        header.column.columnDef.header,
                        header.getContext()
                      )}
                </th>
              ))}
            </tr>
          ))}
        </thead>
        <tbody>
          {table.getRowModel().rows.map((row) => (
            <tr key={row.id}>
              {row.getVisibleCells().map((cell) => (
                <td key={cell.id}>
                  {flexRender(cell.column.columnDef.cell, cell.getContext())}
                </td>
              ))}
            </tr>
          ))}
        </tbody>
      </table>
  );
};

export default Table;

In the code above we have users data to populate the table. We are using createColumnHelper function to create columnHelper which is then used to define an array of columns. These columns decide how data will appear in the table. It creates columns according to the header we have provided. In this case, it is "Name," "Age," "Email," etc. We can customize cell rendering behavior by providing cell property. If it is not provided then it indicates that the default cell rendering behavior will be used.

useReactTable hook is used to set up a table component with data and column configurations. This configuration decides how data will be rendered in the table. We are using table.getHeaderGroups() and table.getRowModel().rows for generating the header and body of the table.

After some styling, the table would look like the below image:

Step 3: Customize accordingly

You can now start customizing the table according to your needs. You can add search, sorting, pagination, or any other features. TanStack provides the hooks and ease to add all this functionality. You can refer to their official documentation here.

Conclusion

TanStack's table could be a great option for your next table. Its headless UI makes design integration effortless and its rich feature set makes it simple to create pagination, sorting, filtering, and other features. For further clarity, explore additional examples in the documentation.

Happy coding!
