Hello Coders! 👋 😊
In this article, I would like to show you how to create a dynamic table in React.
Before we start, I would highly recommend you to check out runnable examples for the solution on our website:
How to create customized dynamic table in React
The final effect of this post:
Below example presents how to create a dynamic table from an array. Example table should consist of a header and some data records. While creating such records use map()
function to convert them into elements.
Remember that each record should have a unique key 🗝️ - it helps React optimally manage changes in the DOM. Such a key may be, for example, the id
assigned to an element of the table.
import React from 'react';
const tableStyle = {
border: '1px solid black',
borderCollapse: 'collapse',
textAlign: 'center',
width: '100%'
}
const tdStyle = {
border: '1px solid #85C1E9',
background: 'white',
padding: '5px'
};
const thStyle = {
border: '1px solid #3498DB',
background: '#3498DB',
color: 'white',
padding: '5px'
};
const App = () => {
const students = [
{ id: 1, name: 'Bob', age: 25, favFruit: '🍏' },
{ id: 2, name: 'Adam', age: 43, favFruit: '🍌' },
{ id: 3, name: 'Mark', age: 16, favFruit: '🍊' },
{ id: 4, name: 'John', age: 29, favFruit: '🍒' }
];
return (
<div>
<table style={tableStyle}>
<tbody>
<tr>
<th style={thStyle}>Id</th>
<th style={thStyle}>Name</th>
<th style={thStyle}>Age</th>
<th style={thStyle}>Favourite Fruit</th>
</tr>
{students.map(({ id, name, age, favFruit }) => (
<tr key={id}>
<td style={tdStyle}>{id}</td>
<td style={tdStyle}>{name}</td>
<td style={tdStyle}>{age}</td>
<td style={tdStyle}>{favFruit}</td>
</tr>
))}
</tbody>
</table>
</div>
);
};
export default App;

That's how it works.

Sortable columns could be useful too.
Usually sortable columns are something done in backend. YMMV of course but past a certain point its actually more effective to do pagination and sorting in the database request since its optimized for this kind of work.
That ain't difficult, you just have to manipulate the data structure using selectors, a selector library like re-select to be more specific and run a sort method on the array.
Well you can make it more dynamic
By take the object keys and run on map to create a to each of them
This approach is no so much dynamic because you can use this only for one senerio
Thank you for your comment! 👍
In the next post, I will try to make a more dynamic solution. 🚀
More dynamic solution us send array of object
With name and other properties of th like colspan
Would it be a good design principle to have the style code in the object? Maybe it would create too much overhead and be a potential vector for errors? Could it potentially affect performance?
The code has a bug. It assumes the objects are sorted by "id." I introduced a bug by switching "id" values.
How about this suggestion? It fixes the "bug" I introduced.
Is it possible to create to create a react table that adds several rows of input types(number/email) when you click a button
