js获取table中的值

<table id="myTable">
  <tr>
    <td>Row1 Cell1</td>
    <td>Row1 Cell2</td>
    <td>Row1 Cell3</td>
  </tr>
  <tr>
    <td>Row2 Cell1</td>
    <td>Row2 Cell2</td>
    <td>Row2 Cell3</td>
  </tr>
</table>

// 获取第二行第三列的单元格值
var cellValue = document.getElementById('myTable').rows[1].cells[2].innerHTML;
console.log(cellValue); // 输出: Row2 Cell3

var row = document.getElementById('myTable').rows[1];
for (var i = 0; i < row.cells.length; i++) {
  console.log(row.cells[i].innerHTML);
}
// 输出:
// Row2 Cell1
// Row2 Cell2
// Row2 Cell3

var table = document.getElementById('myTable');
for (var i = 0; i < table.rows.length; i++) {
  for (var j = 0; j < table.rows[i].cells.length; j++) {
    console.log(table.rows[i].cells[j].innerHTML);
  }
}

window.onload = function() {
  var cellValue = document.getElementById('myTable').rows[1].cells[2].innerHTML;
  console.log(cellValue);
};
