I am finishing up a table for an IEEE publication but I have a problem because the table is pushed outside of the margins of the paper as you see below:
I am not sure why that is happening. Although I noticed that the "keyword" column might be the item responsible for this behavior because if some of the keywords are composed of a small word, than this problem is less visible (but still present). Also the second problem, very likely caused by the length of the "keyword" column, is that this causes a misalignment of the headers to the right but they should be in the middle.
Below is what I have obtained so far:

I have researched this problem quite a bit and came across this source, this other source. They both were useful to have an understanding of the margins but still they could not be used to solve the issue I have.
I dug more into the problem and find out this source and also this one. However, despite useful, those last two sources were not able to lead me to a proper conclusion.
Please if anyone had the same problem, point out to a proper solution.

Thanks to a user the third column is updated to "words" values. However this is causing an incorrect behavior of the column as you can see below.
