关于这方面的大量文档，我已经完成了所有这些。然而，没有人完全回答我的问题我想用Coldfusion编辑电子表格。我将在这里强调EDIT，因为基本上我想要做的是打开一个已经有模板的电子表格并插入一些数据。我见过的许多方法都涉及将数据从电子表格读入一些查询对象，编辑它然后将其写回来，这不可避免地搞砸了很好的模板格式。
我虽然这可能有用，但是当我尝试编写文件时，我得到一个NullPointerException。一个变量似乎正好拿起电子表格模板。
<cfscript>
a = SpreadSheetRead("#theFileCopy#");
SpreadsheetAddRow(a,"150,ENGL,95,Poetry 1",8,1);
SpreadsheetWrite(a,"#theFileCopy#","yes");
</cfscript>

我现在正尝试使用此方法从电子表格中删除其他工作表。
<cfspreadsheet action="read" src="#theFileCopy#" name="spreadSheetVar" >
<cfset spreadsheetRemoveSheet(spreadsheetVar,"Sheet1")>
<cfset spreadsheetRemoveSheet(spreadsheetVar,"Sheet2")>
<cfset spreadsheetRemoveSheet(spreadsheetVar,"Sheet3")>
<cfspreadsheet action="write" filename="#theFileCopy#" name="spreadsheetVar" overwrite="true" >
<cfoutput>Finished</cfoutput>
删除sheet3行可以使这个工作。一旦我将sheet3添加到卸妆器，我就会得到一个nullpointer。 Sheet3肯定存在。
