DashR DataTable

Dash Python
1

Hello Everyone. I am extremely new to R and Dash. I am having a problem with callbacks and DataTable. I have 4 inputs from the Dropdown and the output from the callback should be DataTable. I’ve uploaded csv file from local PC. The inputs are from the csv. The dataTable from CSV should be displayed after choosing options from dropdown.

I need code snippet for the app callback function for Dash DataTable. Thank you.

htmlDiv(list(
htmlLabel(‘Choose Category of product’,style = list(color = colors$text1)),
dccDropdown(
id = ‘category’,
options= option_category,
placeholder=“Select a category”,
)
),style = list(width = ‘25%’, display = ‘inline-block’)
),
htmlDiv(list(
htmlLabel(‘Choose Region of product’,style = list(color = colors$text1)),
dccDropdown(
id=‘region’,
options=option_region,
placeholder=“Select a region”,

    )
  ), style = list(width = '25%', flaot = 'display', display = 'inline-block')
  ),
  
  htmlDiv(list(
    htmlLabel('Choose Account of product',style = list(color = colors$text1)),
    dccDropdown(
      id = 'account',
      options= option_account,
      placeholder="Select an account",
      
    )
  ),style = list(width = '25%', flaot = 'display', display = 'inline-block')),
  htmlDiv(list(
    htmlLabel('Choose Brand of product',style = list(color = colors$text1)),
    dccDropdown(
      id = 'brand',
      options= option_brands,
      placeholder="Select a Brand",

app$callback(
output = list(id=‘table’, property=‘data’),
params = list(input(id=‘category’, property=‘value’),
input(id=‘region’, property=‘value’),
input(id=‘account’, property=‘value’),
input(id=‘crossfilter-yaxis-type’, property=‘value’)),
