JQuery :: Snapping Effect With .slideDown() And Tables?

Not sure if this is a problem or I just need some help. I would like to have a table cell be able to slide down smoothly. The problem is that to calculate the height to slide down, it formats the text to some width (looks like the width of the browser window) other than the actual width of the cell. When it goes to do the slide, it uses this calculated height, and then snaps to the actual height based on the real width of the cell (this can go either up or down).

I have a very simple example below. Click on the first text string. There is no CSS, so that's not the problem. The table has a width on it. If your browser window is wide enough, it slides smoothly. If you make it narrow enough to what might make it wrap an additional line of text, you'll see it slide down smoothly to the pre-calculated height and than snap to the actual height. In this example, it will snap up because the width set on the table is wider than the browser window.

If no width is set on the table, it scrolls smoothly as expected. But in real life, we need to control the width of columns. Hopefully there is some approach I can apply to make this slide smoothly.
