Styling showcase
Colors, text rotation and number formats
Below we show you two ways how to create styled tables with
openxlsx2 one using the high level functions to style
worksheet areas and one using the bare metal approach of creating the
identical table. We show both ways to create styles in
openxlsx2 to show how you could build on our functions or
create your very own functions.
The example below, with increased column width.
the quick way: using high level functions
# add some dummy data
set.seed(123)
mat <- matrix(rnorm(28 * 28, mean = 44444, sd = 555), ncol = 28)
colnames(mat) <- make.names(seq_len(ncol(mat)))
border_col <- wb_colour(theme = "1")
border_sty <- "thin"
# prepare workbook with data and formated first row
wb <- wb_workbook() %>%
wb_add_worksheet("test") %>%
wb_add_data("test", mat) %>%
wb_add_border("test", "A1:AB1",
top_color = border_col, top_border = border_sty,
bottom_color = border_col, bottom_border = border_sty,
left_color = border_col, left_border = border_sty,
right_color = border_col, right_border = border_sty,
inner_hcolor = border_col, inner_hgrid = border_sty
) %>%
wb_add_fill("test", "A1:AB1", color = wb_colour(hex = "FF334E6F")) %>%
wb_add_font("test", "A1:AB1", name = "Arial", bold = "1", color = wb_colour(hex = "FFFFFFFF"), size = "20") %>%
wb_add_cell_style("test", "A1:AB1", horizontal = "center", textRotation = "45")
