Q: bibliography splits across columns and pages I have this bibliography below a nice long table which is the appendix as in the image below.  The problem is that a single ciation splits across columns and pages. I wonder if this is normal?  I checked many papers and they have like more than 300 citaions but didn't have this problem.
If I want to fix this, is there any method? 
In section XIV of this document, they mentioned about \IEEEtriggeratref{}. However, this only work if I use one time like \IEEEtriggeratref{9} which would move the ref[9] to the new column. If I used both \IEEEtriggeratref{9} \IEEEtriggeratref{19} in two lines then only \IEEEtriggeratref{19} effects the result.
In summary I have two questions: 

*

*Is it normal and okay to split citations across columns and pages like that? I have checked many articles in the field but didn't found any. 

*How can I fix that? Above I mentioned about \IEEEtriggeratref{}but it seems like it only works partially as I can't use it for two or more places of splitted citations.

A: Regarding your second question:
You can prevent all line breaks in bibliography entries by setting the penalty for a page break within a paragraph to 10000, because every entry is one paragraph. To smuggle this extra penalty into the bibliography only, insert one line near the end of your document as follows:
\begin{multicols}{2}
    \section{reference}
    \nocite{*}
    \bibliographystyle{IEEEtran}
    \def\BIBdecl{\interlinepenalty=10000 } % insert this line
