A. excel只能打开一个表格打开另外一个表格第一个就会被关闭只显示第二个是什么问题啊
原因是设置了不能预览多文档。
1、首先按“win+R”组合键打开运行窗口，输入“regedit”，回车确定。

2、然后在弹出来的窗口中定位找到该路径HKEY_CLASSES_ROOT\Excel.Sheet.12和HKEY_CLASSES_ROOT\Excel.Sheet.8。

3、然后更改HKEY_CLASSES_ROOT\Excel.Sheet.12里面的注册表，打开shell\open，删除里面的ddeexec文件夹。

4、然后打开command文件夹，双击里面的注册表command。将里面的文件改为如下：xbBV5!!!!!!!!!MKKSkEXCELFilesVijqBof(Y8w!FId1gLQ%1。
/iknow-pic.cdn.bcebos.com/a71ea8d3fd1f4134136f11682a1f95cad1c85e4f"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/a71ea8d3fd1f4134136f11682a1f95cad1c85e4f?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/a71ea8d3fd1f4134136f11682a1f95cad1c85e4f"/>
5、紧接着然后同样的方法去Excel.Sheet.8里面shell\open，删除ddeexec文件夹，然后也是在command里面修改注册表文件：xbBV5!!!!!!!!!MKKSkEXCELFilesVijqBof(Y8w!FId1gLQ%1。
/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a139a5e40f6f803918fa0ecc064"target="_blank"title="点击查看大图"class="illustration_alink">/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a139a5e40f6f803918fa0ecc064?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/562c11dfa9ec8a139a5e40f6f803918fa0ecc064"/>
6、最后就可以解决问题了。
