<script src="https://cdn.jsdelivr.net/npm/jquery/dist/jquery.min.js"></script>

<table id="myTable">
  <tr>
    <th>Name</th>
    <th>Age</th>
  </tr>
</table>

<script>
$(document).ready(function() {
  // 动态添加行和列
  var newRow = $("<tr>");
  var nameCell = $("<td>").text("John");
  var ageCell = $("<td>").text("25");
  newRow.append(nameCell, ageCell);
  $("#myTable").append(newRow);
});
</script>

var table = $("#myTable");

var rowCount = table.find("tr").length;
var columnCount = table.find("tr:first th").length;
var cellContent = table.find("tr:eq(1) td:eq(0)").text();
