通过 C++ 使用 JavaScript 自动调整行高以进行渲染

通常情况下，为了在单元格中显示全部文本，可以在Microsoft Excel中以普通视图（100%的缩放）自动调整行高。这允许在普通视图中完全显示文本，即使打印或保存为PDF，文本也会正确显示。
然而，在某些情况下，自动调整行高在普通视图中效果良好，但切换到打印视图或保存为PDF时，文本会被剪裁。请检查源文件【Book1.xlsx】及截图。
如果你想防止在已保存的 PDF 文件中被裁剪的文本，可以使用 AutoFitterOptions.forRendering 选项自动调整行高。

现在，在输出的 PDF 文件中文本不再被截断。
