JavaScript 假设有一个4行td的table,将table里面的td顺序颠倒

let oTab = document.getElementById("tab1");
let oBody = oTab.tBodies[0];
let oTrs = oBody.rows;
let a = [];
for (let index = 0; index < oTrs.length; index++) {
  const element = array[index];
  a.push(element);
}
a.reverse();
for (let i = 0; i < a.length; i++) {
  const element = a[i];
  oBody.appendChild(element);
}

let oTab = document.getElementById("tab1");
let oBody = oTab.tBodies[0];
let oTrs = oBody.rows;
let aRows = Array.prototype.slice.call(oRow, 0);
aRows.reverse();
for (let i = 0; i < aRows.length; i++) {
  const element = aRows[i];
  oBody.appendChild(element);
}
