Here's a quick live demo of how you can use HTML local storage to save a list of high scores, then retrieve it and put the data into a table structure. The demonstration script takes a list of high scores, stores it to local storage, retrieves it from local storage, then displays it in a table.

Since localStorage isn't supported by Stack Snippet, here is a JSFiddle that demonstrates the code: https://jsfiddle.net/fsze55x7/1/

HTML:

    
Name
Score

JS:

var hst = document.getElementById("highscores");

var highScores = [
    {name: "Maximillian", score: 1000},
    {name: "The second guy", score: 700},
    {name: "The newbie", score: 50},
];

localStorage.setItem("highscores", JSON.stringify(highScores));

var retrievedScores = JSON.parse(localStorage.getItem("highscores"));

for (var i = 0; i < retrievedScores.length; i++) {
    hst.innerHTML += "" + retrievedScores[i].name + "" + retrievedScores[i].score + "";
}
