make blank columns as transparent

blank columns are set as transparent. This is a shortcut function that will delete top and bottom borders, change background color to transparent, display empty content and set blank columns' width.

empty_blanks(x, width = 0.05, unit = "in", part = "all")

Arguments

x

a flextable object

width

width of blank columns (.1 inch by default).

unit

unit for width, one of "in", "cm", "mm".

part

partname of the table (one of 'all', 'body', 'header', 'footer')

Other sugar functions for table style: align(), bg(), bold(), color(), fontsize(), font(), highlight(), italic(), line_spacing(), padding(), rotate(), valign()
