I'm using the lastest aastex61 package along with deluxetables. My table is only about 1/2 a column wide, and I'm trying to get it to takeup the entire column... What am I doing wrong?

```
\documentclass[twocolumn]{aastex61}
...
\begin{deluxetable}{r|ccc}[h!]
\tablecolumns{4}
\tablewidth{1.0\columnwidth} 
\tablecaption{Schechter Function Parameters} 
\tablehead{ z & log($\phi^{*}$) &  $\alpha$ &  $M^{*}_{\rm UV}$ }
\startdata
    8 & -3.75 & -2.13 & -20.52 \\
    9 & -3.94 & -2.24 & -20.39 \\
    10 & -4.13 & -2.35 & -20.25 \\ 
    11 & -4.29 & -2.47 & -20.11 \\ % Extrapolated from here
    12 & -4.49 & -2.58 & -19.98 \\
    13 & -4.69 & -2.69 & -19.84 \\
    14 & -4.89 & -2.81 & -19.71 \\
    15 & -5.08 & -2.92 & -19.57 \\
    16 & -5.28 & -2.03 & -19.44 \\
\enddata  
\label{tab:schecParams}
\tablecomments{Table comments.}
\end{deluxetable}

```

It still looks like this
