How can i make this from string to HTML?

Question

so i came across this problem where my code gets spitted to string instead of html that im trying to achieve.My question is how can i transform this into innerHTML before spitting? Is it even possible to do this if i push it to the array? My goal is to make this like "to do list app" that has multiple inputs that spit each value to each row.

class Forma extends React.Component {

constructor(){
  super()
  this.state ={
    name: '',
    birth: '',
    age: '',
    items: []
  }
  this.handleInputChange = this.handleInputChange.bind(this)
  this.submitItem = this.submitItem.bind(this)
}

handleInputChange(event){
let name = event.target.name
let birth = event.target.birth
let age = event.target.age
let value = event.target.value

this.setState({ [name] : value, [birth] : value, [age] : value})
}

submitItem (){
  let items = this.state.items
  let item = this.state.name
  let birth =this.state.birth
  let age = this.state.age
  let i = "<th>"
  let z = "</th>"

  let all =i + item + z + i + birth + z + i + age +z
  items.push(all)
 
  
  this.setState({ items: items})
}


  render(){
    return (
      <div className="App">
        <h1>To do List</h1>
        <input type="text" name="name" onChange={this.handleInputChange}></input>
        <input type="text" name="birth" onChange={this.handleInputChange}></input>
        <input type="text" name="age" onChange={this.handleInputChange}></input>
          <button onClick={this.submitItem}>Submit</button>
          

          {this.state.items.map((all) => {
            
            return(
              <tr>{all}<button type="submit" className="delete">Delete</button></tr>

           
            );
          })}
          
      </div>
    );
  }

}

From the docs: dangerouslysetinnerhtml can be used to render html from string

dangerouslySetInnerHTML is React’s replacement for using innerHTML in the browser DOM. In general, setting HTML from code is risky because it’s easy to inadvertently expose your users to a cross-site scripting (XSS) attack. So, you can set HTML directly from React, but you have to type out dangerouslySetInnerHTML and pass an object with a __html key, to remind yourself that it’s dangerous.

<tr dangerouslySetInnerHTML={{all}}><button type="submit" className="delete">Delete</button></tr>
