How to create an HTML table from an array of objects?-CodePudding

I need to generate a table from an array of objects.

For example, the array is:

let arr = [{name: 'Player1',score:10},
{name: 'Player2',score: 7},
{name: 'Player3',score:3}]

And the HTML output should be:

Name	Score
Player1	10
PLayer2	7
Player3	3

I could not think of a way to achieve this through vanilla JS. Also, after the table is created, how will I apply CSS to it?

Any help would be appreciated.

You can loop through the array and for each element add a row to a newly forged table that will be added to the document at the end.

This is a demo:

let players = [
  {name: 'Player1',score:10},
  {name: 'Player2',score: 7},
  {name: 'Player3',score:3}
];

const newTable = document.createElement("table");
newTable.innerHTML = "<thead><th>Player</th><th>Score</th></thead>";
for(player of players){
    const newRow = document.createElement("tr");
    const tdPlayer = document.createElement("td");
    const tdScore = document.createElement("td");
    tdPlayer.textContent = player.name;
    tdScore.textContent = player.score;    
    newRow.appendChild(tdPlayer);
    newRow.appendChild(tdScore);
    newTable.appendChild(newRow);
}

const target = document.getElementById('target');
target.appendChild(newTable);

table{
  border: solid 1px black;
}

table td{
  border: solid 1px black;
}

<div id="target">
</div>

You can use something like

<body>
<div >
    <table>
        <thead>
            <tr>
                <th>player</th>
                <th>score</th>
            </tr>
        </thead>
        <tbody></tbody>
    </table>
</div>
<script>
    const data = [{ name: 'Player 1', score: 10 },
    { name: 'Player 2', score: 7 },
    { name: 'Player 3', score: 3 }]

    const table = document.querySelector('tbody')
    data.forEach((item) => {
        table.innerHTML = table.innerHTML   `<tr>
                <td>${item.name}</td>
                <td>${item.score}</td>
            </tr>`
    })
</script>
