Giving the DIV (or table cells) a defined width and height will make the rendering smoother. The content could be inserted using DOM methods, rather than innerHTML, but the impact of this change is going to be minimal.
Rather than inserting the content directly it could be stored in a string or array. A counter would be needed to determine when all values are received. Then setInterval could be used to insert the values.
