## A Simple Workbook

#```ruby

#Using Custom Styles

#```ruby
# Each cell allows a single, predified style.
# When using add_row, the value in the :style array at the same index as the cell's column will be applied to that cell.
# Alternatively, you can apply a style to an entire row by using an integer value for :style.
