Plotting tables in facets using ggplot2-CodePudding

I am looking for a way to plot some table data in facets using ggplot2.

Below are sample data and some code that sort of produces a plot of what I am looking for. However, using geom_text() makes it difficult to align the lines, and I have problems with text being cropped when I combine the facetted table-plot with other plots.

Thanks in advance

Libray and sample data text_data

library(tidyverse)

text_data <- data.frame(
  rep = 1:5,
  time = rnorm(5, 2, 0.2),
  x = sample(100:130, 5),
  y = sample(40:50, 5),
  z = rnorm(5, -1, 0.3)
)


# Text data in wide format
text_data
#>   rep     time   x  y         z
#> 1   1 2.192189 129 47 -1.308432
#> 2   2 2.161335 105 46 -1.186042
#> 3   3 2.340631 106 48 -1.270763
#> 4   4 2.136504 124 44 -1.332719
#> 5   5 2.148028 108 42 -1.249902

Text data in the table format I would like to plot, each rep should be a facet

text_data %>%
  pivot_longer(cols = -rep) %>%
  knitr::kable(digits = 1)

rep	name	value
1	time	2.2
1	x	129.0
1	y	47.0
1	z	-1.3
2	time	2.2
2	x	105.0
2	y	46.0
2	z	-1.2
3	time	2.3
3	x	106.0
3	y	48.0
3	z	-1.3
4	time	2.1
4	x	124.0
4	y	44.0
4	z	-1.3
5	time	2.1
5	x	108.0
5	y	42.0
5	z	-1.2

Some NOT OPTIMAL to code that produces a facetted plot to show kind of what I am looking for

ggplot(data = text_data)  
  geom_text(
    y = 0.9,
    x = 0.5,
    aes(label = paste("Time:", round(time, 1), "seconds"))
  )  
  geom_text(
    y = 0.7,
    x = 0.5,
    aes(label = paste("X: ", x))
  )  
  geom_text(
    y = 0.5,
    x = 0.5,
    aes(label = paste("y: ", y))
  )  
  geom_text(
    y = 0.3,
    x = 0.5,
    aes(label = paste("z: ", round(z, 1)))
  )  
  facet_grid(rows = vars(rep))  
  theme_minimal()

Here's an approach using the gridExtra package.

library(tidyverse)
library(gridExtra)

text_data <- data.frame(
  time = rnorm(5, 2, 0.2) ,
  x = sample(100:130, 5),
  y = sample(40:50, 5),
  z = rnorm(5, -1, 0.3)
) %>% 
  mutate(
    across(.f = ~ as.character(round(., 2))),
    time = paste(time, "seconds")
    )
  
grob_list <- map(1:nrow(text_data), ~ {
  text_data[.x,] %>% 
    as_vector() %>% 
    as.matrix(ncol = 1) %>% 
    tableGrob(theme = ttheme_minimal())
})

grid.arrange(grobs = grob_list, ncol = 1)
