\section{Basic Table with Booktabs}

The \texttt{booktabs} package provides professional-quality horizontal rules. Use \verb|\toprule|, \verb|\midrule|, and \verb|\bottomrule| instead of \verb|\hline|.

\begin{table}[h]
\centering
\caption{Quarterly Revenue by Region (in \$M)}
\label{tab:basic}
\begin{tabular}{@{}lrrrr@{}}
\toprule
\textbf{Region} & \textbf{Q1} & \textbf{Q2} & \textbf{Q3} & \textbf{Q4} \\
\midrule
North America & 142.3 & 156.8 & 163.2 & 189.4 \\
Europe        & 98.7  & 104.2 & 112.5 & 128.1 \\
Asia-Pacific  & 76.4  & 82.1  & 91.8  & 105.3 \\
Latin America & 34.2  & 37.6  & 41.3  & 48.7 \\
Middle East   & 18.9  & 21.4  & 24.7  & 29.2 \\
\midrule
\textbf{Total} & \textbf{370.5} & \textbf{402.1} & \textbf{433.5} & \textbf{500.7} \\
\bottomrule
\end{tabular}
\end{table}

\section{Table with Multirow and Multicolumn}

The \texttt{multirow} package allows cells to span multiple rows, while \verb|\multicolumn| handles column spanning.

\begin{table}[h]
\centering
\caption{Software Development Team Allocation}
\label{tab:multirowcol}
\begin{tabular}{@{}llccc@{}}
\toprule
\textbf{Department} & \textbf{Team} & \textbf{Engineers} & \textbf{Designers} & \textbf{PMs} \\
\midrule
\multirow{3}{*}{Product} & Core Platform & 12 & 2 & 2 \\
                          & Mobile Apps   & 8  & 3 & 1 \\
                          & API Services  & 6  & 0 & 1 \\
\midrule
\multirow{2}{*}{Infrastructure} & Cloud Ops     & 5  & 0 & 1 \\
                                 & Security      & 4  & 0 & 1 \\
\midrule
\multirow{2}{*}{Data} & Analytics     & 7  & 1 & 1 \\
                       & ML Platform   & 9  & 1 & 1 \\
\midrule
\multicolumn{2}{@{}l}{\textbf{Total}} & \textbf{51} & \textbf{7} & \textbf{8} \\
\bottomrule
\end{tabular}
\end{table}

\section{Colored Rows (Alternating)}

Use the \texttt{colortbl} package with \verb|\rowcolor| for alternating row colors.

\begin{table}[h]
\centering
\caption{Programming Language Popularity Index (2025)}
\label{tab:colored}
\begin{tabular}{@{}clrrr@{}}
\toprule
\textbf{Rank} & \textbf{Language} & \textbf{Index (\%)} & \textbf{Change} & \textbf{Since} \\
\midrule
\rowcolor{lightblue}
1  & Python     & 28.11 & +3.48  & 2001 \\
2  & JavaScript & 16.38 & --0.72 & 1995 \\
\rowcolor{lightblue}
3  & Java       & 12.21 & --1.15 & 1995 \\

10 & Swift      & 2.34  & +0.18  & 2014 \\
\bottomrule
\end{tabular}
\end{table}

\section{Wide Table with TabularX}

The \texttt{tabularx} package provides an \texttt{X} column type that automatically adjusts width to fill the available space.

\begin{table}[h]
\centering
\caption{Project Milestones and Status}
\label{tab:tabularx}
\begin{tabularx}{\textwidth}{@{}lXcl@{}}
\toprule
\textbf{Milestone} & \textbf{Description} & \textbf{Due Date} & \textbf{Status} \\
\midrule
M1: Requirements & Gather and document functional and non-functional requirements from all stakeholders. Conduct user interviews and competitive analysis. & 2025-01-15 & \textcolor{green!60!black}{Complete} \\
\addlinespace

\bottomrule
\end{tabularx}
\end{table}

\section{Long Table (Spanning Multiple Pages)}

The \texttt{longtable} package handles tables that may break across pages, with repeated headers.

\begin{longtable}{@{}clp{5cm}r@{}}
\caption{HTTP Status Codes Reference}\label{tab:longtable} \\
\toprule
\textbf{Code} & \textbf{Status} & \textbf{Description} & \textbf{Category} \\
\midrule
\endfirsthead

\multicolumn{4}{@{}l}{\textit{Continued from previous page}} \\
\toprule
\textbf{Code} & \textbf{Status} & \textbf{Description} & \textbf{Category} \\
\midrule
\endhead

\midrule
\multicolumn{4}{r@{}}{\textit{Continued on next page}} \\
\endfoot

\bottomrule
\endlastfoot

200 & OK & Request succeeded. The response body contains the requested resource. & Success \\
\addlinespace
201 & Created & Request succeeded and a new resource was created. Typically returned after POST requests. & Success \\
\addlinespace
204 & No Content & Request succeeded but the server has no content to return. Common for DELETE operations. & Success \\
\addlinespace
301 & Moved Permanently & The requested resource has been permanently moved to a new URI. Clients should update bookmarks. & Redirection \\
\addlinespace
302 & Found & The resource temporarily resides at a different URI. The client should continue using the original URI. & Redirection \\
\addlinespace
304 & Not Modified & The resource has not been modified since the last request. The client can use its cached version. & Redirection \\
\addlinespace
400 & Bad Request & The server cannot process the request due to malformed syntax or invalid parameters. & Client Error \\
\addlinespace
401 & Unauthorized & Authentication is required. The request lacks valid credentials for the target resource. & Client Error \\
\addlinespace
403 & Forbidden & The server understood the request but refuses to authorize it. Authentication will not help. & Client Error \\
\addlinespace
404 & Not Found & The server cannot find the requested resource. The URI may be invalid or the resource may not exist. & Client Error \\
\addlinespace
405 & Method Not Allowed & The HTTP method is not supported for this resource. Check the Allow header for permitted methods. & Client Error \\
\addlinespace
409 & Conflict & The request conflicts with the current state of the resource. Common in concurrent update scenarios. & Client Error \\
\addlinespace
422 & Unprocessable Entity & The request was well-formed but contains semantic errors. Often used for validation failures. & Client Error \\
\addlinespace
429 & Too Many Requests & The client has sent too many requests in a given time window. Implement backoff and retry. & Client Error \\
\addlinespace
500 & Internal Server Error & An unexpected condition prevented the server from fulfilling the request. & Server Error \\
\addlinespace
502 & Bad Gateway & The server acting as a gateway received an invalid response from an upstream server. & Server Error \\
\addlinespace
503 & Service Unavailable & The server is temporarily unable to handle the request due to maintenance or overload. & Server Error \\
\addlinespace
504 & Gateway Timeout & The upstream server did not respond within the allowed time frame. & Server Error \\
