Method: Writeexcel::Format#set_bold

Defined in:
lib/writeexcel/format.rb

#set_bold(weight = nil) ⇒ Object

Set the bold property of the font:

Default state:      bold is off
Default action:     Turn bold on
Valid args:         0, 1 [1]

format.set_bold()   # Turn bold on
1

Actually, values in the range 100..1000 are also valid. 400 is normal,

700 is bold and 1000 is very bold indeed. It is probably best to set the value to 1 and use normal bold.
