How to calculate the sum of every column ?

[Fernando0016]

Hello,

Here is an extract from my dataset, it's a dataframe that describes the frequency of terms that occur in a collection of documents. I would like to propose a chart that displays the most frequent terms (columns). i need to do this automatically

Can you help me ?
