Question

我正在使用函数GetStringWidth()来计算MultiCell()所需的行数。

列宽为75，GetStringWidth()的结果为212，因此我的文字需要3行才能充分适应我的MultiCell()。

问题是使用MultiCell()时此字符串的输出超过4行。然后我意识到这可能是因为输出中的字符串的字间距过大，但没有理由这样做。

使用MultiCell()输出字符串时，请查看下面的单词间距（您可以在上面的标题中看到正常的字间距）：

这是使用Cell()函数使用相同字符串进行测试时的输出（忽略格式化）。差异很明显：

看来GetStringWidth()与MultiCell()无法正确比较，或者MultiCell()的字间距大于Cell()。

我尝试过使用多种字体，因此我可以确认这不是字体特定问题。

有人可以帮我确定为什么会发生这种情况吗？我的代码如下。谢谢。
