database - 使用 ColdFusion 在 Excel 列中进行文本换行或自动宽度调整

Question

我从数据库中提取数据并在 Excel 中为客户呈现。唯一的问题是某些数据对于列来说太大了，并且由于数据是动态的(当然)我基本上需要能够进行一些文本换行或根据需要扩展列的宽度。

我的代码贴在下面

<!---Used for streaming to browser--->
<cfset context = getPageContext()>
<cfset context.setFlushOutput(false)>
<cfset response = context.getResponse().getResponse()>
<cfset out = response.getOutputStream()>
<cfset response.setContentType("application/vnd.ms-excel")>
<cfset response.setHeader("Content-Disposition", "attachment; filename=ERD_Report.xls" )>

<!---Create Workbook and Sheets in workbook--->
<cfset wb = createObject("java","org.apache.poi.hssf.usermodel.HSSFWorkbook").init()/>
<cfset sheet1 = wb.createSheet("ERD Report")/>

<cfset cellStyleStatic = createObject("java","org.apache.poi.hssf.usermodel.HSSFCellStyle")/>
<cfset cellHSSFFont = createObject("java","org.apache.poi.hssf.usermodel.HSSFFont")/>

<!---Title--->
<cfset fontTitle = wb.createFont()/>
<cfset fontTitle.setFontName("Calibri") />
<cfset fontTitle.setFontHeightInPoints(javacast("int",11))/>

<cfset styleTitle.setfont(fontTitle)/>

<cfset styleTitle.setBorderBottom(styleTitle.BORDER_THIN)/>
<cfset styleTitle.setBorderLeft(styleTitle.BORDER_THIN)/>

<cfset styleCenter = wb.createCellStyle()/>
<cfset styleCenter.setAlignment(cellStyleStatic.ALIGN_CENTER)/>

<cfset styleDate = wb.createCellStyle()/>
<cfset styleDate.setDataFormat(createObject("java","org.apache.poi.hssf.usermodel.HSSFDataFormat").getBuiltinFormat("m/d/yy"))/>

我尝试使用 SpreadsheetFormatCell，as posted here ，虽然我知道它只会文本换行 1 个单元格。所完成的只是让我的 Excel 页面显示 HTTP 500 页面。

我也试过 SpreadsheetFormatColumn 方法，as posted here , 并且有很多错误。

任何帮助都会很棒，如果有另一篇与这篇文章类似的文章，请指出我的方向。我总是有可能错过它。

使用 ColdFusion 9，对吧？这令人沮丧，因为 ColdFusion 9 文档声明它可以工作，但它被严重破坏了。我认为这可能已在最近的 ColdFusion 11 中得到修复，但它仍然使用多个旧版本的 Apache POI 库。

尝试使用 spreadsheetWrite()。我发现使用标签与脚本保存时存在差异:

注意:如果可以使用 CFLive.net 或 TryCF.com 完成此类测试，那就太好了，但出于安全原因，它们不允许生成文件。
