Tips for customizing the appearance of a React-Table header when sorting data

How can I change the header's background color in react-table based on a selected item? For example, if I click on ID, the ID header should change its background color to red.

I have tried various methods to update the background color upon selection.

Custom CSS

.ReactTable .rt-th  {
    -webkit-box-flex: 1;
    -ms-flex: 1 0 0px;
    flex: 1 0 0;
    white-space: nowrap;
    text-overflow: ellipsis;
    padding: 7px 5px;
    overflow: hidden;
    transition: 0.3s ease;
    transition-property: width, min-width, padding, opacity;
    background: green;
  }

Answer №1

I concur with the previous statement regarding using state to toggle the className. Here is a simple example consisting of JavaScript, CSS, and HTML. The isActive property is initially set to false and changes its value when the handleClick method is triggered.

class App extends React.Component {

constructor (props) {
super (props);
    this.state = { isActive:false }
this.handleClick = this.handleClick.bind(this);
}

handleClick () {
this.state.isActive ? this.setState({ isActive: false }) : this.setState({ 
isActive: true })
}

render() {
return <div>
  <div onClick={this.handleClick} className = { this.state.isActive ? "red" : "green"} > Background Color </div>
</div>;
}}

React.render(<App />, document.getElementById('app'));

The CSS styling is relatively simple:

.red 
background-color: red 

.green 
background-color: green

As for the HTML markup:

<div id="app"></div>

Is it possible to activate the state and then evaluate the condition during component rendering?
