Thank for your support.

import justpy as jp

cell_style = '''(params) => {{
    if (params.value > 3){
      return {'color': 'red'}
    }
    
    return {'color': 'green'}
   
}}'''


grid_options = {
    #'rowHeight': 40,
    'columnDefs': [
      {'headerName': "Make", 'field': "make"},
      {
        'headerName': "Model", 
        'field': "model",
 
      },
      {  'headerName': "Price", 'field': "price", 'cellStyle': cell_style},
    ],
    'rowData': [
      {'make': "Toyota", 'model': "Celica", 'price': '4' },
      {'make': "Ford", 'model': "Mondeo", 'price': '3' },
      {'make': "BMW", 'model': "v1", 'price': '6' }
    ],
}

def grid_test():
    wp = jp.WebPage()
    grid = jp.AgGrid(a=wp, options=grid_options, theme='ag-theme-material')
    # grid.html_columns = [1,2]

    print(grid)
    
    return wp

app = jp.app
jp.justpy(grid_test)
