Question

您好，我在构建此表时遇到了问题。请尽快给我答复。因此我尝试了以下方法：

\documentclass{article}

% Definitions
\usepackage{lscape}
\usepackage[height=25cm]{geometry}
\usepackage{timetable}
\usepackage{array}
\usepackage{multirow}

\begin{document}
\begin{table}[htbp]
  \centering
  %\caption{Add caption}
    \begin{tabular}{|c|c|c|c|c|c|c|}
    \hline
    \multirow{3}[4]{*}{S.No} & \multirow{4}[5]{*}{Activity} & \multicolumn{4}{c|}{\multirow{2}[2]{*}{2017 }}\\
         & \multicolumn{5}{c|}{} \\
\cline{2-3} & \cline{3-5}           & Feb-Mar   & Apr-Jun    & Jul-Sept    & Oct-Dec   \\
    \hline
     1& Literature on Polynomial Optimization   &       &       &       &        \\
    \hline
     2&Solution to Question 1A   &       &       &       &        \\
    \hline
     3&Solution to Question 1b    &       &       &       &       \\
    \hline
     4& Solution to Question 2  &       &       &       &        \\
    \hline
     5& Conjecture    &       &       &       &        \\
    \hline
    \end{tabular}%
  \label{tab:addlabelkiki}%
\end{table}%
\end{document}
