Colocando tabela e imagem na mesma página paisagem

Question

Estou tentando colocar uma mesa longa e três imagens na mesma página paisagem. Aqui está um MWE:

\documentclass[11pt]{article}

\usepackage{graphicx}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{lipsum}
\usepackage{pdflscape}
\usepackage{multirow}
\usepackage{afterpage}
\usepackage[a4paper, portrait, margin=1in]{geometry}

\begin{document}

\lipsum[1-2]

% want to put a table and images here

\afterpage{
\begin{landscape}
\begin{table}[ht]
    \small
    \centering
    \def\arraystretch{1.5}

    \begin{tabularx}{0.991\linewidth}{lccccccccccc} \toprule
         & \multicolumn{3}{c}{No Clustering} & \multicolumn{4}{c}{$K$-means Clustering} & \multicolumn{4}{c}{Hierarchical Clustering} \\ 
         & \multicolumn{3}{c}{--} & \multicolumn{4}{c}{$K=19$} & \multicolumn{4}{c}{$K=5$} \\   
         \cmidrule(r){2-4} \cmidrule(lr){5-8} \cmidrule(l){9-12}
         % this is what has to be replaced with xtable
         & Lasso & Elastic Net & pcLasso & gLasso & ogLasso & sgLasso & pcLasso & gLasso & ogLasso & sgLasso & pcLasso \\ \midrule

        Sig. Coef. & $14$ & $28$ & $16$ & $443$ & $1$ & $52$ & $76$ & $2714$ & $1$ & $772$ & $46$ \\
        Sig. Groups & -- & -- & -- & $1$ & $0$ & $1$ & $15$ & $2$ & $0$ & $1$ & $5$ \\ 
        %
        \bottomrule
    \end{tabularx}
    \caption{The performance of various models on the leukemia data set.}

\end{table}

\begin{figure}[ht]
    \centering
    \includegraphics[width = 0.48\textwidth]{img1.pdf}
    \includegraphics[width = 0.48\textwidth]{img2.pdf}
    \includegraphics[width = 0.48\textwidth]{img3.pdf}
    \caption{The ROC curves for the leukemia data set.}
    \label{leuk_ROC}
\end{figure}

\end{landscape}
}

\lipsum[3-7]

\end{document}

O objetivo é fazer com que a tabela se estenda pela página e as três imagens fiquem alinhadas abaixo dela. No entanto, aqui está o meu resultado:

Claramente, não funcionou. Alguma sugestão sobre como isso pode ser corrigido?

EDITAR

Fiz algumas pequenas modificações no código e alterei a saída. Mas a questão ainda permanece.

Answer 1

Apenas substituindo [ht]por [p]a tabela e a figura, coloquei-as em uma página paisagem. ( drafté adicionado para ignorar as imagens ausentes.)
