Why does the flextable looks different in R Viewer vs. in HTML - r

How can you control line thickness in html outputs using flextable? It looks fine in the RStudio viewer. I think this might not have to do with flextable and might just be a problem with however flextable gets turned to HTML, but not sure where that occurs.
library(dplyr)
library(flextable)
library(officer)
iris %>% head(n=4) %>% flextable() %>%
bg(bg = "#00557F", part = "header") %>%
bold(part = "header") %>%
color( color = "white", part = "header") %>%
border_outer(border = big_border, part = "all" ) %>%
border_inner_h( border = std_border, part = "all" ) %>%
border_inner_v( border = std_border, part = "all" ) %>%
autofit() %>% save_as_html(path = 'ex.html')

kableExtra table repeat_header being strange

I've finally made my dream table with kableExtra, but it's doing very weird things with kable_styling(latex_options=c("repeat_header")), where it's writing the headings over my column labels. Here I'm using the example dataset diamonds. It is also moving the first column below where it should be (red arrows in picture).
(Also can't download LaTex because of work authorization issues, so that's not an option)
Thanks for all the help!
library(knitr)
library(kableExtra)
library(dplyr)

knitr.table.toprule = '\\toprule',
knitr.table.midrule = '\\midrule',
knitr.table.bottomrule = '\\bottomrule'

How to write a table with hyperlinks in officedown powerpoint with R?

I can print my data with gt table and create hyperlinks for different cells, as shown below by knitting an HTML file:
library(dplyr)
library(gt)
raw_dat <- mtcars[1:15, ] %>% rownames_to_column(var = "id") %>% select(id, mpg)
df <- tibble(
name = raw_dat$id,
link = 'https://www.cars.com//')
df %>%
mutate(link = sprintf('<p>%s', link, raw_dat$mpg),
link = map(link, gt::html)) %>%
gt
I want to print the same output to a powerpoint slide and preserve the links. I understand that I cannot use 'ph_with' with an object of class "c('gt_tbl', 'list')". So I was wondering what else I can do to print a table with hyperlinks in powerpoint.
NEW <- read_pptx("Presentation1.pptx") %>%
add_slide(., layout = "Blank", master = "Office Theme") %>%
ph_with(raw_dat,
location = ph_location(left = 0, top = 0, width = 13.33, height = 7.5))
This is a solution with flextable that is supported by officer.
library(tibble)
library(dplyr)
library(flextable)
library(officer)
raw_dat <- mtcars[1:15, ] %>% rownames_to_column(var = "id") %>% select(id, mpg)
df <- tibble(name = raw_dat$id, link = 'https://www.cars.com//')
ft <- flextable(df) %>%
mk_par(j = "link", value = as_paragraph(hyperlink_text(x = name, url = link))) %>%
autofit()
read_pptx() %>%
add_slide() %>%
ph_with(ft, location = ph_location_type()) %>%
print(target = "toto.pptx")
PS: I am not sure that I answer the question as it is generated with officer, not officedown, but your example is not a R Markdown example. I assumed you wanted to use officer.

Fix flextable dimensions in powerpoint

I am using flextable and officer in my shiny app to allow users to create powerpoint slides from the app. I am having a bit of a problem with flextable adjusting itself to the dimensions of the placeholder specified in the slide master of my ppt template.
Also I am aware that autofit in flextable does not work for pptx.
Below are two examples, in the first example (with the mtcars data) the table seems to be fine in terms of automatically adjusting the font sizes to match the width and height given.
df <- as_tibble(mtcars, rownames = "cars") %>%
mutate(Date = as.Date("2020-01-01"))
select(-4,5)
flextable::flextable(df) %>%
fit_to_width(max_width = 5.928819) %>%
height(height = 4.6319444/nrow(df)) %>%
color(i=~str_detect(cars,"Merc"), j=~cars, color = "red", part = "body") %>%
bg(i = ~str_detect(cars,"Merc"), j=~cars, bg="black", part = "body") %>%
color(i=~str_detect(cars,"Hornet"), j=~cars, color = "blue", part = "body") %>%
color(i=~mpg < 20, j=~mpg, color = "green", part = "body") %>%
#my_theme() %>%
print(preview = "pptx")
However in the second example with the air quality data the table is always longer that the height specified and the font size does not automatically adjust. Can anyone shed light on why one table works but the other doesnt?
df4 <- mutate(airquality, Ozone = 1000*Ozone) %>%
head(30) %>%
mutate(word = "ABCDEF")
flextable::flextable(df4) %>%
fit_to_width(max_width = 5.9288199) %>%
height(height =4.6319444/(nrow(df4))) %>%
add_header_row(top = TRUE, values = c("quality", "time", "rand"), colwidths = c(4,2,1)) %>%
add_footer_lines("some text can go here") %>%
colformat_num(j=~Ozone, big.mark = ",") %>%
colformat_double(j=~Wind, suffix = " $") %>%
vline_left(border = fp_border(color = "red", style="solid", width = 1)) %>%
vline_right(border = fp_border(color = "red", style="solid", width = 1)) %>%
vline(j=~Temp, border = fp_border()) %>%
set_header_labels(Temp = "Temperature") %>%
#hrule(rule = "exact", part = "body") %>%
print(preview = "pptx")

how to make customised pretty flexable function

I am loving flextable however, incorporating it within my workflow is causing issues in that I am not able to write general purpose functions.
I want a function that would automatically highlight the header and the last row of the table. I am able to do this but I have to specify the name of the first column name. This is simply too much work, is there a work around?
library(tidyverse)
require(flextable)
require(rlang)
# Function that works
my_table <- function(x){
require(flextable)
require(rlang)
x %>%
flextable() %>%
# Header colour and bold
bg(bg = "#e05297", part = "header") %>%
flextable::color(color = "white", part = "header") %>%
# Last row bold and highlight
bold(i = ~rowname == "Total", bold = TRUE) %>%
bg(i = ~rowname == "Total",
bg = "grey",
part = "body")
}
mtcars %>%
rownames_to_column() %>%
adorn_totals("row") %>%
my_table()
# This is a general purpose function which is not working
my_table <- function(x){
require(flextable)
require(rlang)
first_col_name <- colnames(x) %>% .[1]
x %>%
flextable() %>%
# Header colour and bold
bg(bg = "#e05297", part = "header") %>%
flextable::color(color = "white", part = "header") #%>%
# Last row bold and highlight
bold(i = ~eval(rlang::sym(first_col_name)) == "Total", bold = TRUE) %>%
bg(i = ~eval(rlang::sym(first_col_name)) == "Total",
bg = "grey",
part = "body")
}
Any ideas how to make the general purpose my_table function to work
i argument also accepts position (row number) of the dataframe to highlight so you may use nrow to get the last row in the dataframe.
library(flextable)
library(janitor)
my_table <- function(x){
x %>%
flextable() %>%
# Header colour and bold
bg(bg = "#e05297", part = "header") %>%
flextable::color(color = "white", part = "header") %>%
bold(i = nrow(x), bold = TRUE) %>%
bg(i = nrow(x),bg = "grey",part = "body")
}
mtcars %>%
rownames_to_column() %>%
adorn_totals("row") %>%
my_table()

Row heigth with flextable and officer

I have a new computer (read: new versions of everything, including Office 2016)
I created the following code on my previous computer, and all worked fine:
...
control_table <- regulartable(data = data) %>%
theme_box() %>%
rotate(rotation = "btlr", part = "header") %>%
align(align = "left", part = "body") %>%
set_header_labels(Var1 = " " ) %>%
align(align = "left", part = "header") %>%
height(height = 3, part = "header") %>%
width(width = 0.3) %>%
width(j = 1, width = 3.5)
doc <- doc %>%
cursor_reach("The following table indicates the reports") %>%
body_add_flextable(control_table, align = "left")
...
now with my new computer the row height of the header is not being translated into the Word document. dim(control_table) gives the correct row height, but the header row height is not displaying in the word document.
What am I missing?
Word don't handle auto height with rotated headers, then it is necessary to specify rule for row height with function hrule.
library(flextable)
library(officer)
library(magrittr)
control_table <- flextable(data = head(iris)) %>%
theme_box() %>%
rotate(rotation = "btlr", part = "header") %>%
align(align = "left", part = "body") %>%
set_header_labels(Var1 = " " ) %>%
align(align = "left", part = "header") %>%
height(height = 2, part = "header") %>%
hrule(i = 1, rule = "exact", part = "header")
doc <- read_docx() %>%
body_add_flextable(control_table, align = "left") %>%
print(target = "example.docx")
