Use `state activeId and display innertable`. This is working example.
<!-- begin snippet: js hide: false console: true babel: true -->
<!-- language: lang-js -->
const data = [ { name: "Rama singh1", noc: "noc1", final: "final1", today: "today1", upto: "upto1" }, { name: "Rama singh2", noc: "noc2", final: "final2", today: "today2", upto: "upto2" }, { name: "Rama singh3", noc: "noc3", final: "final3", today: "today3", upto: "upto3" }, { name: "Rama singh4", noc: "noc4", final: "final4", today: "today4", upto: "upto4" } ];
const JobsTable = props => ( <div className="table-responsive"> <table className="table table-hover" id="dashboard"> <thead> <tr className="text-center"> <th scope="col">Technology</th> <th scope="col">Total Resumes</th> <th scope="col">Job Title</th> <th scope="col">Total Score</th> <th scope="col">Average Score</th> </tr> </thead> <tbody /> </table> </div> ); const Tableone = props => ( <div className="row"> <div className="col-12"> <div className="table-responsive"> <table className="table table-hover" id="dashboard"> <thead> <tr className="text-center"> <th /> <th scope="col">Recruiter Name</th> <th scope="col">Number of ID</th> <th scope="col">Yesterday's Final Score</th> <th scope="col">Score added today</th> <th scope="col">Updo Date Final Score</th> </tr> </thead> <tbody className="text-center"> {props.data && props.data.length > 0 && props.data.map((item, key) => { return ( <React.Fragment key={key}> <tr key={key} onClick={() => props.clickHandler(key)}> <td align="center"> <input type="checkbox" /> </td> <td>{item.name}</td> <td className="font-weight-bold">{item.noc}</td> <td>{item.final}</td> <td className="font-weight-bold">{item.today}</td> <td className="font-weight-bold">{item.upto}</td> </tr> {props.activeId === key ? ( <tr> <JobsTable /> </tr> ) : null} </React.Fragment> ); })} </tbody> </table> </div> </div> </div> ); class App extends React.Component { state = { activeId: "" }; clickHandler = id => { if (id === this.state.activeId) this.setState({ activeId: "" }); else this.setState({ activeId: id }); }; render() { return ( <Tableone data={data} activeId={this.state.activeId} clickHandler={this.clickHandler} /> ); } } ReactDOM.render(<App/>, document.getElementById('root'));

That's *property spread notation*. It was added in ES2018, but long-supported in React projects via transpilation (as "JSX spread attributes" even though you could do it elsewhere, too, not just attributes).
`{...this.props}` *spreads out* the "own" properties in `props` as discrete properties on the `Modal` element you're creating. For instance, if `this.props` contained `a: 1` and `b: 2`, then
<Modal {...this.props} title='Modal heading' animation={false}>
would be the same as
<Modal a={this.props.a} b={this.props.b} title='Modal heading' animation={false}>
But it's dynamic, so whatever "own" properties are in `props` are included.
Since `children` is an "own" property in `props`, spread will include it. So if the component where this appears had child elements, they'll be passed on to `Modal`. Putting child elements between the opening tag and closing tags is just syntactic sugar&nbsp;&mdash; the good kind&nbsp;&mdash; for putting a `children` property in the opening tag. Example:
<!-- begin snippet: js hide: true console: true babel: true -->
<!-- language: lang-js -->
class Example extends React.Component { render() { const { className, children } = this.props; return ( <div className={className}> {children} </div> ); } } ReactDOM.render( [ <Example className="first"> <span>Child in first</span> </Example>, <Example className="second" children={<span>Child in second</span>} /> ], document.getElementById("root") );
<!-- language: lang-css -->
.first { color: green; } .second { color: blue; }
<!-- language: lang-html -->
<div id="root"></div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
<!-- end snippet -->
Spread notation is handy not only for that use case, but for creating a new object with most (or all) of the properties of an existing object&nbsp;&mdash; which comes up a lot when you're updating state, since you can't modify state directly:
this.setState(prevState => { return {foo: {...prevState.foo, a: "updated"}}; });
That replaces `this.state.foo` with a new object with all the same properties as `foo` except the `a` property, which becomes `"updated"`:
<!-- begin snippet: js hide: true console: true babel: false -->
<!-- language: lang-js -->
const obj = { foo: { a: 1, b: 2, c: 3 } }; console.log("original", obj.foo); // Creates a NEW object and assigns it to `obj.foo` obj.foo = {...obj.foo, a: "updated"}; console.log("updated", obj.foo);
