Why can't I replace a string in a column?

Post Body

Trying to replace some HTML code (string) I have in a column:

df['popup_html_mobile'].str.replace(r"<table>", "<table height='200' width='20%'>", n=1, regex=True)

Ok, great, this works fine. A new dataframe was printed where every row in the column has had its <table> tag replaced.

Let me just try to actually modify the whole column now...

df['popup_html_mobile'] = df['popup_html_mobile'].str.replace(r"<table>", "<table height='200' width='20%'>", n=1, regex=True)

Nope. No effect at all. The string remains unchanged.

What am I doing wrong here?
