In this code, I change the behavior of the Cell object in a subclass called FitCell. The behavior of FitCell is changed by overriding the CellRenderer.
Actually, I'm not really changing the behavior of the renderer, but I'm changing some things the moment the renderer instance is created (before anything else happens). I define a padding for the cell, I define a font and a leading for the Paragraph and I calculate the font size of the Paragraph so that the text fits the cell. I first define a font size of 100 (which is huge), but none of the content will eventually have a font size of 100, because I first make sure that all the text fits the height of the cell; then I make sure that all the text fits the width of the cell.
The result is that all the text fits the cell.
