vline: Set vertical borders to the right of selected columns

In flextable: Functions for Tabular Reporting

Set vertical borders to the right of selected columns

Description

vline() draws a vertical line to the right of each selected column by setting the right border of cells at column j (and the left border of cells at column j + 1 so that the line renders consistently across output formats).

Use the j selector to target specific columns. When j is NULL (the default) the border is added to the right of every column, producing a full grid of inner vertical lines.

For the outer edges of the table, use vline_left() and vline_right() instead; those always target the very first or very last column.

Usage

vline(x, i = NULL, j = NULL, border = NULL, part = "all")

Arguments

x	a 'flextable' object, see flextable-package to learn how to create 'flextable' object.
i	row selector, see section Row selection with the i parameter in <Selectors in flextable>.
j	column selector, see section Column selection with the j parameter in <Selectors in flextable>.
border	border properties defined by a call to officer::fp_border()
part	part selector, see section Part selection with the part parameter in <Selectors in flextable>. Value 'all' can be used.

Examples

library(officer)
std_border <- fp_border(color = "orange")

ft <- flextable(head(iris))
ft <- border_remove(x = ft)

# add vertical borders to the right of every column
ft <- vline(ft, border = std_border)
ft
