这个错误是因为`getBoundingClientRect()`方法不适用于Vue组件的ref属性。要解决这个问题，你可以使用`$el`来访问DOM元素并调用`getBoundingClientRect()`方法。修改代码如下：

startDrag(event) {
  event.preventDefault();

  // 计算初始位置
  const boundingRect = this.$refs.buttonRef.$el.getBoundingClientRect();
  // 其他代码...
},

通过`this.$refs.buttonRef.$el`可以获取到引用的DOM元素，然后再调用`getBoundingClientRect()`方法即可。这样就能正确获取按钮元素的位置信息了。记得在其他地方也要相应地修改代码。希望对你有帮助！

要设置自定义调整列宽，你可以使用CSS中的`table-layout`属性和`width`属性来实现。具体步骤如下：

1. 在CSS样式中，将`table-layout`属性设置为`fixed`。这将使表格的列宽度固定。
2. 为每个表格单元格（`td`和`th`）设置一个固定的宽度（或者使用百分比），以确定每列的默认宽度。
3. 在需要调整列宽的地方，添加一个可调整宽度的元素，比如一个拖动条。
4. 使用JavaScript来处理拖动条的事件，并根据拖动条的位置调整表格列的宽度。

以下是一个示例代码段，演示了如何实现自定义调整列宽的功能：

<!DOCTYPE html>
<html>
<head>
<style>
table {
  border-collapse: collapse;
  width: 100%;
  table-layout: fixed;
}

td, th {
  border: 1.5px solid black;
  padding: 5px;
}

th {
  background-color: #f2f2f2;
}

.column-resizer {
  background-color: #ddd;
  width: 6px;
  height: 100%;
  position: absolute;
  right: 0;
  top: 0;
  cursor: col-resize;
}

</style>
</head>

</table>

<script>
var columnResizer = document.createElement('div');
columnResizer.className = 'column-resizer';

document.addEventListener('DOMContentLoaded', function() {
  var table = document.getElementById('myTable');
  var resizableColumns = table.querySelectorAll('th');

  resizableColumns.forEach(function(column) {
    var resizer = columnResizer.cloneNode(true);
    column.appendChild(resizer);

    resizer.addEventListener('mousedown', function(e) {
      var originalWidth = column.offsetWidth;
      var startX = e.pageX;

      document.addEventListener('mousemove', resizeColumn);
      document.addEventListener('mouseup', stopResize);

      function resizeColumn(e) {
        var width = originalWidth + (e.pageX - startX);
        column.style.width = width + 'px';
      }

      function stopResize() {
        document.removeEventListener('mousemove', resizeColumn);
        document.removeEventListener('mouseup', stopResize);
      }
    });
  });
});
</script>

</body>
</html>

在这个示例中，每个表头单元格都添加了一个可调整宽度的元素`column-resizer`，当你点击并拖动该元素时，可以调整相应列的宽度。你可以根据需要修改其中的样式和事件处理程序来满足你的要求。

<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>鉴本</title> <style> table { border-collapse: collapse; width: 100%; } th, td { padding: 8px; text-align: left; border: 1px solid #ddd; } th { background-color: #f2f2f2; } table img { max-width: 150px; height: auto; } <!-- //图片大小调整 --> .popup { position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-color: rgba(0, 0, 0, 0.8); display: flex; align-items: center; justify-content: center; } .popup img { max-width: 100%; max-height: 100%; cursor: zoom-out; } .sticky-header { position: sticky; top: 0; background-color: #f5f5f5; /* 可根据需要设置背景色 */ } <!-- //放大图片设置 --> </style> </head> <body> <div> <button onclick="addRow()">新增一行</button> <button onclick="addColumn()">添加一列</button> <button onclick="deleteRow()">删除行</button> <button onclick="deleteColumn()">删除列</button> <div> <div id="popup" class="popup" style="display: none;"> <img id="popupImg"> </div> <table id="myTable"> <thead> <tr> <th style="width: 20px;">列1</th> <th>列2</th> <th>列3</th> </tr> </thead> <thead class="sticky-header"> 这样调整后列宽仍然没有变化

抱歉，我之前的回答可能有误导性。确实，使用 `width` 样式来调整表头单元格的宽度并不会影响表格列的宽度。

要实现自由调整表格列宽的功能，你可以使用 JavaScript 来处理拖动调整列宽的操作。下面是一个示例代码，可以在你的网页中实现该功能：

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>鉴本</title>
  <style>
    table {
      border-collapse: collapse;
      width: 100%;
    }

    th, td {
      padding: 8px;
      text-align: left;
      border: 1px solid #ddd;
    }

    th {
      background-color: #f2f2f2;
    }
  </style>
</head>
<body>
  <table id="myTable">
    <thead>
      <tr>
        <th style="width: 20px;">列1</th>
        <th>列2</th>
        <th>列3</th>
      </tr>
    </thead>
    <tbody>
      <!-- 表格内容 -->
    </tbody>
  </table>

  <script>
    var table = document.getElementById("myTable");
    var columns = table.querySelectorAll("th");
    var isResizing = false;
    var startX, startWidth;

    for (var i = 0; i < columns.length; i++) {
      var column = columns[i];
      column.addEventListener("mousedown", function (event) {
        isResizing = true;
        startX = event.pageX;
        startWidth = this.offsetWidth;
      });

      column.addEventListener("mousemove", function (event) {
        if (!isResizing) return;
        var width = startWidth + (event.pageX - startX);
        this.style.width = width + "px";
      });

      column.addEventListener("mouseup", function () {
        isResizing = false;
      });
    }
  </script>
</body>
</html>

在这个示例代码中，我添加了一些 JavaScript 代码，用于处理拖动调整列宽的操作。当你在表头单元格上按下鼠标按键并移动时，表头单元格的宽度会根据鼠标移动的距离进行调整。

请注意，这只是一个基本的示例代码，你可以根据需要进行修改和美化。希望这次能够满足你的需求。如果还有其他问题，请随时提问。
