If you make it into Word, from my experience, you can make more design details. Steps are very simple: go into Insert Tab, choose Table and choose number of rows and columns.
In excel, from my experience, you can do less design details. It is little more complicated to change line thickness and some other details but you can much easier add diagram from table data. Excel is already big table.
Both programs have advantages and disadvantages. What do you use for make tables?
