improve the attached excel report

I am attaching a rather ugly report on absenteism. The coder (?) will improve its look both from the point of view of graphics and from the point of view of readibility. This is a work for an expert of business management with some graphic skills. The coder will have to understand the subject of the report and produce a report that will be both better-looking and easier to read for a manager. An added chart would be great. An external application will input data thru COM into the Excel sheet. So all functions should be properly set and cells where to input data properly stated.
