vue.runtime.esm.js:619 [Vue warn]: Error in created hook: "TypeError: Cannot read properties of undefined (reading 'toggleRowSelection')"

这个报错是由于在created钩子函数中调用了一个未定义的函数toggleRowSelection，从而导致了TypeError: Cannot read properties of undefined错误。

为了解决这个问题，你可以将这个函数调用移至mounted钩子函数中。在mounted钩子函数中，组件已经被挂载到页面上，并且所有的DOM操作都已经完成，这时候调用函数是安全的。

此外，还需要检查是否存在其他可能的原因导致这个错误。比如，检查是否正确引入了相关的库或组件，以及确保相关的数据或变量被正确定义或赋值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
