I'm using IEEEtran.cls for a journal paper and I'm unable to make a one column abstract using the inbuilt commands in IEEEtran: \onecolumn, \twocolumn. Switching between the two flushes the page and starts a new one. \nopagebreak doesn't work. Tried putting samepage tags. Didn't help either. I'm compiling using Xelatex. Any way to make one column and two column in the same page?

From your description, it seems that the two tabular environments are being moved to a floats only page; if this is the case, the float will be placed centered vertically on the page; to change this behaviour, you can change the value for the length \@dblfptop, using
\makeatletter
\@dblfptop 0pt
\makeatother
A complete example:
\documentclass[journal]{IEEEtran}
\makeatletter
\@dblfptop 0pt
\makeatother

An image of the top portion of the second page, showing the float at the top:
You can put a wide image that spans both columns at the top of the page, either by using a two column float (figure*) or by using the optional argument of \twocolumn which specifies a spanning text to be put over the columns, so
\documentclass[conference]{IEEEtran}
\usepackage{graphicx}
\begin{document}
\twocolumn[%
{\includegraphics[width=\textwidth]{example-image}}%
]
\loop
\stepcounter{enumi}
\ifnum\value{enumi}<1000
\roman{enumi}
\repeat
\end{document}

A minimal working example:
Note: For some reason
\lipsum[1]inside theabstractenvironment must be enclosed with brackets and must be at least one character before (it can be be~, but no a normal space), but nothing of this is needed for real text.
