You can use DT package for datatable for that. You need to use html tags with escape = FALSE. Have a look at the modified your code below:

  library(shiny)
  library(DT)
  ui <- fluidPage(dataTableOutput("table"))

  server <- function(input, output) {
    output$table <- renderDataTable({
      data <- datatable(data.frame(c(1, 2), row.names = c("A1", "A2")), rownames = T, escape = FALSE)
      })
  }

  shinyApp(ui = ui, server = server)

You get a table which looks like this:

EDIT:

You can add subscript for renderTable by using html tags with sanitize.text.function = function(x) x. The code would be as shown below:

 library(shiny)

    ui <- fluidPage(tableOutput("table"))

    server <- function(input, output) {
      output$table <- renderTable({data <- data.frame(c(1, 2),
                                                      row.names = c("A1", "A1"))}, rownames = T, sanitize.text.function = function(x) x)}

    shinyApp(ui = ui, server = server)

The output table will look as follows:
