如题如图
小弟自己是打到这边
\begin{table}[!t]
\centering
\caption{Table to test captions and labels.}
\begin{tabular}{ l l l l l }
\toprule
Input: & \multicolumn{4}{l}{Tap weight vector}\\
& \multicolumn{4}{l}{input vector} \\
& \multicolumn{4}{l}{and desired output}\\
Output: & \multicolumn{4}{l}{Filter output}\\
& \multicolumn{4}{l}{tap-weight vector update}\\
\toprule
\multicolumn{1}{l}{1. Filtering:}\\
\multicolumn{5}{c}{$y(n) = \mathbf{w}^T(n) \mathbf{x}(n)$}\\
\multicolumn{1}{l}{2. Error estimation:}\\
\multicolumn{5}{c}{Eq}\\
\multicolumn{1}{l}{3. Tap-weight vector adaption:}\\
\multicolumn{5}{c}{Eq}\\
\bottomrule
\end{tabular}
\label{table:test00}
\end{table}
但努力过后还是打不出来
跑出来的格式很奇怪
麻烦各路大神帮忙解惑一下
非常感谢
