我是Angular的新手，使用Angular material 5 mat-table并尝试将表导出到excel文件中。我使用了 SheetJS XLSX 包。
下面是我的代码：
Table.component.html：
Message: OpenQA.Selenium.StaleElementReferenceException : stale element reference: element is not attached to the page documentTable.component.ts：
<mat-table #table [dataSource]="dataSource" matSort>
<!-- ID Column -->

</mat-table>

</div>
我正在使用npm i XLSX并出现一些错误。
错误：
错误范围（0）：A1：A0
[对象错误] {说明：“错误范围（...）”，消息：“错误范围（...”，名称：“错误”，ngDebugContext：对象{...}，堆栈：“错误：不好...“}
这是怎么了？
还有什么其他方法可以从Angular Material Table导出excel，我也需要对表进行分页。
答案 0 :(得分：1)
SheetJS XLSX与Angular Material 5及更高版本不兼容，因为它读取表格标签，其中从病区的材质5开始使用垫子表格。

为时已晚，但我尝试... 我发现了相同的问题，并通过以下方式解决了问题： 从
更改HTML标签 <mat-table...>...</mat-table>至<table mat-table...>...</table>
<mat-header-cell ...>...</mat-header-cell>至<th mat-header-cell....>...</th>
<mat-cell...>...</mat-cell>至<td mat-cell ...>...</td>
仅此而已，XLSX不能识别物料标签，但可以识别物料属性。
