A couple weeks ago I set-out to build a prototype for some friends of their web application ideas. They already had a design built partially in Material UI. In the past I’ve found most CSS frameworks and libraries to be a colossal pain, but after poking around I decided that MUI is a pretty awesome tool that I get to work with. It has led me to believe that if you’re building a component library for your own needs, you’re wasting time and the companies time (unless you want to do it for fun).
Data Tables in MUI
The examples in the docs are somewhat clear, but not entirely.
I had a demo recently to my friend but I could not for the life of me get the data to render properly. Here’s an example of my table code.
import React, { useState, useEffect } from 'react';
import { DataGrid } from '@mui/x-data-grid';
import { CircularProgress } from '@mui/material';
export default function ProjectsList(props) {
const columns = [
{ field: 'name', headerName: 'Name', width: 130 },
{ field: 'duedate', headerName: 'Due Date', width: 130 },
{ field: 'description', headerName: 'Description', width: 130 }
];
const projects = [
{name: 'Adams new project', duedate: 'March 31, 2023', description: 'Gotta build the prototype'},
{name: 'Adams new project 2', duedate: 'March 31, 2023', description: 'Gotta build the prototype'},
{name: 'Adams new project 3', duedate: 'March 31, 2023', description: 'Gotta build the prototype'},
{name: 'Adams new project 4', duedate: 'March 31, 2023', description: 'Gotta build the prototype'},
]
if(isLoading) {
return (<CircularProgress />);
} else {
return (
<DataGrid rows={projects} columns={columns} pageSize={5} />
)
}
}
You would expect a table with 4 rows and 3 columns to render. I got the columns but no row data. I saw that the pagination said 4 items on the page on page 1 of 1, but there were no grids.
The tricky part is the documentation isn’t that great. It missed one key element: talking about the row height requirement. An easy fix:
Change this:
<DataGrid rows={projects} columns={columns} pageSize={5} />
To this:
<DataGrid rows={projects} columns={columns} pageSize={5} autoHeight={true} />
There you have it! A table that renders.
