cell values were formatted using base 1024. Use base 1024 for both to report
the same values.

Modern browsers allow decomposing table markup equally well as nested div
constructs, therefor migrate our <div> table markup to actual <table> tags
but keep the old table/tr/th/td CSS classes for now to allow for a smooth
theme transition.
