将 pgfplottable 拆分为两列

我的附录中有一张长表，其中包含大量数据，我想将其拆分成两列（即并排放置两个表以占用更少的边）。这可能吗？

我的代码如下：

我找到了一个适合我的解决方案。我没有尝试将表格拆分为两列，而是使用键select equal part entry of将数据拆分为两组匹配的列。它看起来像这样：

\pgfplotstabletypeset[
    columns={S,SNAME,KAL,SMA,WMA,S,SNAME,KAL,SMA,WMA},
    display columns/0/.style={select equal part entry of={0}{2}, column name=$i$},
    display columns/1/.style={select equal part entry of={0}{2},string type, column name={Stock}},
    display columns/2/.style={select equal part entry of={0}{2}, column name=$P_{kalman}$},
    display columns/3/.style={select equal part entry of={0}{2}, column name=$P_{SMA}$},
    display columns/4/.style={select equal part entry of={0}{2}, column name=$P_{WMA}$},
    display columns/5/.style={select equal part entry of={1}{2}, column name=$i$},
    display columns/6/.style={select equal part entry of={1}{2},string type, column name={Stock}},
    display columns/7/.style={select equal part entry of={1}{2}, column name=$i$}
    display columns/8/.style={select equal part entry of={1}{2}, column name=$P_{SMA}$},
    display columns/9/.style={select equal part entry of={1}{2}, column name=$P_{WMA}$},
    every head row/.style={before row=\caption{Full experimental data}\label{tab:data}\\\toprule, after row=\midrule\endhead}
    ]{\datatable}
