Interactive tables make bad takes more fun.

A recent tweet provided a (IMO) fairly week argument that paying a QB ends up making your team unsuccessful (no Superbowl wins for the 9 QBs below).

Moo had a good counter-argument (just include the 10th QB) - Tom Brady ruins part of the narrative. Additionally, just include playoff appearances and/or wins.

So let’s make a table of salary data vs playoff appearances! We could make this static (screenshot for Twitter) - but just for funs lets stretch a bit and make an interactive table with nice formatting.

reactable - interactive data tables

reactable is an R wrapper for the react table javascript library. Greg Lin at RStudio recently made this package and you can install it from CRAN with install.packages("reactable"). I adapted this table from some examples at the reactable package site.

Raw data comes from: Pro Football Reference & Over the Cap

A very basic reactable table can be created as so:

playoff_salary %>%
  reactable()

More Complex

At the risk of drawing the rest of the *&?$ing owl here is a more complex interactive table using the same data.

Part 2 of this blogpost will go step-by-step into creating more complex tables, but for now…enjoy and consume at your own risk!

2014-2019 Salary and Playoff Appearances

QBs limited to playoff games where they threw a pass

Raw Code to generate the table

Below is the raw code to generate the table - I’ll do a deeper dive later, but as of now here is the raw code I used, including some HTML and CSS helpers. This is all adapted from the reactable cookbook.

The CSS and HTML helpers do some light-lifting for custom text and borders.

make_color_pal <- function(colors, bias = 1) {
  get_color <- colorRamp(colors, bias = bias)
  function(x) rgb(get_color(x), maxColorValue = 255)
}

good_color <- make_color_pal(c("#ffffff", "#f2fbd2", "#c9ecb4", "#93d3ab", "#35b0ab"), bias = 2)

tbl <- playoff_salary %>%
  arrange(desc(salary)) %>%
  mutate(
    `Salary Rank` = rank(desc(salary)),
    salary = round(salary, 1)
  ) %>%
  select(`Salary Rank`, player:Superbowl, everything()) %>%
  reactable(
    pagination = FALSE,
    compact = TRUE,
    borderless = FALSE,
    striped = FALSE,
    fullWidth = FALSE,
    theme = reactableTheme(
      headerStyle = list(
        "&:hover[aria-sort]" = list(background = "hsl(0, 0%, 96%)"),
        "&[aria-sort='ascending'], &[aria-sort='descending']" = list(background = "hsl(0, 0%, 96%)"),
        borderColor = "#555"
      )
    ),
    defaultColDef = colDef(
      align = "center",
      minWidth = 100
    ),
    columns = list(
      salary = colDef(
        name = "Salary",
        style = function(value) {
          value
          normalized <- (value - min(playoff_salary$salary)) / (max(playoff_salary$salary) - min(playoff_salary$salary))
          color <- good_color(normalized)
          list(background = color)
        },
        cell = JS("function(cellInfo) {
                          return cellInfo.value + 'M'}")
      ),
      Total = colDef(
        style = function(value) {
          value
          normalized <- (value - min(playoff_salary$Total)) / (max(playoff_salary$Total) - min(playoff_salary$Total))
          color <- good_color(normalized)
          list(background = color)
        },
        class = "border-left"
      ),
      player = colDef(
        name = "Name",
        minWidth = 140,
        align = "left"
      )
    )
  )
