推荐答案

你可以通过修改字体来做到这一点：

You can do that by modifiying the font:

Font f1 = FontFactory.getFont(FontFactory.TIMES_ROMAN, 12);
f1.setColor(BaseColor.BLUE);
cell.addfont(f1); 

请检查应用字体的位置，以便更改正确数量的文本。

此外它之后可能需要更改回黑色字体（如果不是某个图层的所有元素都应该更改）。

Please check where to apply the font so that the right amount of text is changed.
Also it might be needed to change back to black font afterwards (if not all elements of a certain layer are supposed to change).
