Unable to sort in asc and desc order in datatable

Dash Python
1

Hi there,
I am new to plotly and just started learning on the go.
So i have a pandas dataframe scrapped from a website which is actucally a table.
I am able to add sorting functionality to columns with integers but i noticed its not working properly.I tried in tweaking lot of this but nothing helped me.Please help me find the mistake happend.I dont know if i have to paste all the code or just the layout and callback.So i am posting all the code.

import dash

link = 'https://www.mohfw.gov.in/'
req = requests.get(link)
soup = BeautifulSoup(req.content, "html.parser")
thead = soup.find_all('thead')[-1]
head = thead.find_all('tr')
tbody = soup.find_all('tbody')[0]
body = tbody.find_all('tr')
head_rows = []
body_rows = []
for tr in head:
    td = tr.find_all(['th', 'td'])
    row = [i.text for i in td]
    head_rows.append(row)
for tr in body:
    td = tr.find_all(['th', 'td'])
    row = [i.text for i in td]
    body_rows.append(row)
df_bs = pd.DataFrame(data=body_rows[:len(body_rows) - 6], columns=head_rows[0])
df_bs.drop('S. No.',axis=1,inplace=True)

Thank you so much and have a nice day.Stay safe
