I am trying to format via css a paricular table as it shows in the below picture:

![My Table](https://i.stack.imgur.com/pJTfv.png)

As I am new to css I am having problems with specifying:

1. Borders: As you can see I want to have different border colors and weights for vertical and horizontal borders; for row names and column name
2. Gap after the 13th column: One solution would possibly be to create a second table and place them next to each other but i wouldn't like to go for that solution
3. Conditional Formating: Could I do that using css or I have to go the [jQuery solution](https://stackoverflow.com/questions/22850562/how-to-have-conditional-formatting-of-data-frames-in-r-shiny)
