Basic Table

library(plotly)

fig <- plot_ly(
  type = 'table',
  columnwidth = c(100, 100),
  columnorder = c(0, 1),
  header = list(
    values = c("Cut","Price"),
    align = c("center", "center"),
    line = list(width = 1, color = 'black'),
    fill = list(color = c("grey", "grey")),
    font = list(family = "Arial", size = 14, color = "white")
  ),
  cells = list(
    values = rbind(diamonds$cut, diamonds$price),
    align = c("center", "center"),
    line = list(color = "black", width = 1),
    font = list(family = "Arial", size = 12, color = c("black"))
  ))

Styled Table

library(plotly)

fig <- plot_ly(
  type = 'table',
  header = list(
    values = c('<b>EXPENSES</b>', '<b>Q1</b>','<b>Q2</b>','<b>Q3</b>','<b>Q4</b>'),
    line = list(color = '#506784'),
    fill = list(color = '#119DFF'),
    align = c('left','center'),
    font = list(color = 'white', size = 12)
  ),
  cells = list(
    values = rbind(
      c('Salaries', 'Office', 'Merchandise', 'Legal', '<b>TOTAL</b>'),
      c(1200000, 20000, 80000, 2000, 1212000),
      c(1300000, 20000, 70000, 2000, 1392000),
      c(1300000, 20000, 120000, 2000, 1442000),
      c(1400000, 20000, 90000, 2000, 1412000)),
    line = list(color = '#506784'),
    fill = list(color = c('#25FEFD', 'white')),
    align = c('left', 'center'),
    font = list(color = c('#506784'), size = 12)
    ))

Table From a Dataframe

library(plotly)

fig <- plot_ly(
  type = 'table',
  header = list(
    values = c("<b>Cars</b>", names(mtcars)),
  align = c('left', rep('center', ncol(mtcars))),
  line = list(width = 1, color = 'black'),
  fill = list(color = 'rgb(235, 100, 230)'),
  font = list(family = "Arial", size = 14, color = "white")
  ),
  cells = list(
    values = rbind(
      rownames(mtcars), 
      t(as.matrix(unname(mtcars)))
    ),
    align = c('left', rep('center', ncol(mtcars))),
    line = list(color = "black", width = 1),
    fill = list(color = c('rgb(235, 193, 238)', 'rgba(228, 222, 249, 0.65)')),
    font = list(family = "Arial", size = 12, color = c("black"))
  ))

Changing Size of Rows and Columns

values <- rbind(c('Salaries', 'Office', 'Merchandise', 'Legal', '<b>TOTAL<br>EXPENSES</b>'), c("Lorem ipsum dolor sit amet, tollit discere inermis pri ut. Eos ea iusto timeam, an prima laboramus vim. Id usu aeterno adversarium, summo mollis timeam vel ad", 
     "Lorem ipsum dolor sit amet, tollit discere inermis pri ut. Eos ea iusto timeam, an prima laboramus vim. Id usu aeterno adversarium, summo mollis timeam vel ad", 
     "Lorem ipsum dolor sit amet, tollit discere inermis pri ut. Eos ea iusto timeam, an prima laboramus vim. Id usu aeterno adversarium, summo mollis timeam vel ad", 
     "Lorem ipsum dolor sit amet, tollit discere inermis pri ut. Eos ea iusto timeam, an prima laboramus vim. Id usu aeterno adversarium, summo mollis timeam vel ad", 
    "Lorem ipsum dolor sit amet, tollit discere inermis pri ut. Eos ea iusto timeam, an prima laboramus vim. Id usu aeterno adversarium, summo mollis timeam vel ad"))

fig <- plot_ly(
  type = 'table',
  columnorder = c(1,2),
  columnwidth = c(80,400),
  header = list(
    values = c('<b>EXPENSES</b><br>as of July 2017', '<b>DESCRIPTION</b>'),
    line = list(color = '#506784'),
    fill = list(color = '#119DFF'),
    align = c('left','center'),
    font = list(color = 'white', size = 12),
    height = 40
  ),
  cells = list(
    values = values,
    line = list(color = '#506784'),
    fill = list(color = c('#25FEFD', 'white')),
    align = c('left', 'center'),
    font = list(color = c('#506784'), size = 12),
    height = 30
    ))

What About Dash?

Dash for R is an open-source framework for building analytical applications, with no Javascript required, and it is tightly integrated with the Plotly graphing library.

Learn about how to install Dash for R at https://dashr.plot.ly/installation.

Everywhere in this page that you see fig, you can display the same figure in a Dash for R application by passing it to the figure argument of the Graph component from the built-in dashCoreComponents package like this:

library(plotly)

fig <- plot_ly() 
# fig <- fig %>% add_trace( ... )
# fig <- fig %>% layout( ... ) 

library(dash)
library(dashCoreComponents)
library(dashHtmlComponents)

app <- Dash$new()
app$layout(
    htmlDiv(
        list(
            dccGraph(figure=fig) 
        )
     )
)

app$run_server(debug=TRUE, dev_tools_hot_reload=FALSE)
