使用aspose創建Excel

Question

嗨，我正在研究Java項目。

我正在為Excel API使用aspose-cell.7.0.0 jar文件。

但是在觸發save方法時出現異常。

這是版本錯誤嗎？

看起來是字體問題，請嘗試以下操作

1. 安裝“ Microsoft TrueType核心字體”，然后再次運行該程序。
2. 從基於命令的Java程序中運行相同的示例。 如果您遇到相同的問題，請在Aspose論壇中報告示例代碼和Java / OS版本。
3. 嘗試使用最新版本的Aspose.Cells for Java，該問題可能已經解決。

我與Aspose一起擔任開發人員推廣人員。
