如何使用javascript从多维数组创建和填充多个表

let multiArray = [[1, 2, 3], [4, 5, 6]];

let table = document.createElement("table");

// 创建表头
let thead = document.createElement("thead");
let tr = document.createElement("tr");
for (let i = 0; i < multiArray[0].length; i++) {
  let th = document.createElement("th");
  th.innerText = "Header " + (i+1);
  tr.appendChild(th);
}
thead.appendChild(tr);
table.appendChild(thead);

// 创建表格内容
let tbody = document.createElement("tbody");
for (let i = 0; i < multiArray.length; i++) {
  let tr = document.createElement("tr");
  for (let j = 0; j < multiArray[i].length; j++) {
    let td = document.createElement("td");
    td.innerText = multiArray[i][j];
    tr.appendChild(td);
  }
  tbody.appendChild(tr);
}
table.appendChild(tbody);

// 将表格添加到页面中的某个元素
document.getElementById("container").appendChild(table);
