DataFrame.to_html col_space parameter to change width of a specific column only
#### Code Sample, a copy-pastable example if possible


#### Problem description

Currently `col_space` changes width of all columns that are present in the dataframe. There must be a way to change the width of a specific column only while converting dataframe to html.

#### Expected Output
`col_space` to accept a list or dict where we can mention the column name to change only a specific column's width.
