You need to be aware that the members of this site are volunteers. They answer on questions in their spare time. In order to be able to answer as many questions as possible, it is normal that that they expect that the questions are clear and comprehensible, that they do not need to search the web for data known to asker etc., that the questions contain MWE (Minimal Working Example, a small but a complete compilable document) that reproduces the problem of interest.

So be so kind, and provide in your question all what you asked in comment. If you not do so, we can only guess about some information, which are essential ion preparation of answer.- For example, the following example, is based in guessing:

IN MWE below is assumed, that your document has two columns.

• In such document for table, which span both columns you should use table* environment.
• Some table cells has very long text. For it is sensible to use column type which breaks text into multiple lines. Example of such column tapes are p{<column width>}, or X and its derivatives from tabularx table environment (as is selected in MWE below).
• Numbers in tale can be simply and concise to write by employing siunitx package.
