I am making a medical program saying what I patient needs, what he has, and what he needs to be tested for.

The format is an editable spreadsheet like excel, however I have no control to do this, and I need to color the lines different colors
|A sickness (Red)| A list of symptoms | A cure | |
|A medicated sickness (Yellow)| A list of symptoms | The cure|
|A cured sickness (Blue)| A list of symptoms| The cure| | |___________________________________________________ |

How can I do this?

Do you have code that actually works with the excel spreadsheet, and you are having trouble figuring out the colors, or are you having trouble figuring out how to work with the spreadsheet period?
