Aufgabenstellung

Table borders are not necessary since they provide no additional information.
Since there is no table labeling, the whole statistics is hard to understand.
Table rows contain different types of information, e.g. "Sold", "On the market" and "Change".
Units (% and $) within the table cells are badly formatted. Those could be extracted and written into the table header.
Some units are explicitly displayed (% and $), others not even defined (last column).
The Dimensions of the table columns are not properly assigned. While the last column is far too wide, others are too short.
Header information of the first column is used in table cells again.
Numbers are aligned left, hence they are hardly comparable and readable.
The serparator of numbers (in table column "units") is missing. Not consistent through whole statistics.
Precision of numbers is not constistent as well.
Confusing naming of table cells, e.g. "Change 2007-2008" references change from March 2007 to March 2008.
Missing percentages for Change from March 2007 to March 2008.

Restructuring of the (sub-)divisions gives a better overview of the data. Major divisions are now "On the market" and "Sold". Those are arranged into subdivisions which represent different timeslots (e.g. March, April 10th).
Percentages are no longer in a seperate column, but added to the data cell of 2008.
Since the main target of the table is to illustrate the changes from 2007 to 2008 we color coded this informtion and rearranged the cells, so that now data of the same type from 2007 and 2008 are adjacent horizontally.
