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

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。
最佳答案
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。
关于database - 使用 ColdFusion 在 Excel 列中进行文本换行或自动宽度调整，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23477840/
