[Tex/LaTex] \vfill and vertical space

Question

In a two-column document, I would like some text to be positioned at the bottom right of the right column. The text is inside tabular and flushright. An MWE is:

\documentclass[twocolumn]{article}
\usepackage{lipsum}
\begin{document}

\lipsum[1-4]
\vfill
\begin{flushright}
  \begin{tabular}[b]{p{3cm} r}
    some text & 0
  \end{tabular}
\end{flushright}

\end{document}

However, there is some vertical space below (see image) which I would like to remove so the part "some text 0" fully aligns with the left column at the bottom.

I believe I would need to edit the spacing for both flushright and tabular in this instance but don't know how (other than just manually adding a negative space via \vspace{-1.5em}). Help appreciated!

EDIT: To explain why I use/need the tabular, here is working example less minimal but more similar to my needs. It already uses some of the answers below.

\documentclass[twocolumn]{article}
\usepackage{lipsum}
\usepackage[demo]{graphicx}
\usepackage{array}
\begin{document}

\lipsum[1-4]
\vspace*{\fill}

\noindent
\makebox[\linewidth][r]{
  \begin{tabular}[b]{ b{3cm} r@{}}
  some long, line-wrapped text &
\includegraphics[width=2cm]{img}
\end{tabular}
}

\end{document}

But there still seems to be some small space below the box.

Answer 1

\documentclass[twocolumn]{article}
\usepackage{lipsum}
\begin{document}

\lipsum[1-4]

\vspace*{\fill}


\noindent
\makebox[\linewidth][r]{some text \quad 0}



\end{document}

Note you want \vspace* not \vfill or the space would be discarded if the column break happened at that point.
