这个错误表示在渲染过程中引用了一个未定义的属性或方法`searchId`。这通常是因为在Vue实例中没有定义`searchId`属性。

要解决这个问题，你需要确保`searchId`属性正确地定义在Vue实例的`data`选项中。请检查你的代码，确保有一个名为`searchId`的属性。

示例代码：

data() {
  return {
    searchId: '', // ensure searchId is defined here
    tableData: [],
    filteredData: []
  }
},

确保在你的Vue组件的`data`选项中有一个名为`searchId`的属性，这样就可以解决这个错误。
