A. excel只能打開一個表格打開另外一個表格第一個就會被關閉只顯示第二個是什麼問題啊
原因是設置了不能預覽多文檔。
1、首先按「win+R」組合鍵打開運行窗口，輸入「regedit」，回車確定。

2、然後在彈出來的窗口中定位找到該路徑HKEY_CLASSES_ROOT\Excel.Sheet.12和HKEY_CLASSES_ROOT\Excel.Sheet.8。

3、然後更改HKEY_CLASSES_ROOT\Excel.Sheet.12裡面的注冊表，打開shell\open，刪除裡面的ddeexec文件夾。

4、然後打開command文件夾，雙擊裡面的注冊表command。將裡面的文件改為如下：xbBV5!!!!!!!!!MKKSkEXCELFilesVijqBof(Y8w!FId1gLQ%1。
/iknow-pic.cdn.bcebos.com/a71ea8d3fd1f4134136f11682a1f95cad1c85e4f"target="_blank"title="點擊查看大圖"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、緊接著然後同樣的方法去Excel.Sheet.8裡面shell\open，刪除ddeexec文件夾，然後也是在command裡面修改注冊表文件：xbBV5!!!!!!!!!MKKSkEXCELFilesVijqBof(Y8w!FId1gLQ%1。
/iknow-pic.cdn.bcebos.com/562c11dfa9ec8a139a5e40f6f803918fa0ecc064"target="_blank"title="點擊查看大圖"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、最後就可以解決問題了。
