It is appearing that your use of Exceltools was the problem. Use ExcelTools.
Another option is to use something like matrixplot with the option heights=histogram

Please reference this topic http://www.mapleprimes.com/questions/37691-How-Do-I-Change-The-Background-Colour
In a nutshell basically use windows desktop setup to alter the colors. Failing wanting to do that you can change the font colors easily with Format->Styles or manage style sets and create your own. As for the background (using the ref above) create a 1x1 table and change the colour in the cell.

This problem could be applied to a similar issue in deciding which lengths to cut in set lengths of framing.
Home depot sells pine colonial casing in 7ft. lengths only. I have 4 windows and one inside door (both sides) to frame. The windows are 2 - 42x20 windows, 1-30x30 window and 1-16x20 window, the door is 72x32.
What is the minimum number 7ft framing pieces I need to finish the job? and how do I cut the wood?
So I want to minimize my waste and hence minimize my spending.

Another less desireable more complex/expensive way to convert the list back into the original number, is to create a procedure that manipulates the list created by convert using commands from the StringTools and ListTools packages.
collect seems to get rid of the negative sign and re-orient the values as well
ee := -ln(-a/(b-c));
ff := combine(ee, symbolic);
Expanding on Kitonums answer we could also create a procedure
listplot(DataTable3[..,1]) #plots the first column of your data
It is possible seeing that you have "******" in one of your answers that you are using "*" for matrix multiplication instead of "."
