SInce you did not paste any code, try this:
library(shiny)
library(DT)
shinyApp(
ui = fluidPage(
DT::dataTableOutput("mtcarsTable")
),
server = function(input, output) {
output$mtcarsTable <- DT::renderDataTable({
DT::datatable(datasets::mtcars[,1:3],
options = list(rowCallback = JS(
"function(nRow) {",
"var full_text = 'Test1';",
"var full_text1 = 'Test2';",
"$('td:eq(0)', nRow).attr('title', full_text);",
"$('td:eq(1)', nRow).attr('title', full_text1);",
"}")
)
)
})
}
)
Try that and see if shiny loads correctly
