[Tex/LaTex] Removing vertical lines in tables

tables

I have the following table.

enter image description here

  1. How can I remove extra falling lines?
  2. How can I make a double line between R43 and R44?

Here is my MWE.

\documentclass[12pt,landscape]{article}

\usepackage[top=20mm,bottom=20mm,left=20mm,right=20mm,marginparwidth=30mm,marginparsep=1mm]{geometry}

\begin{document}


\begin{table}[htb]
  \centering
  \begin{tabular}{|l|l|l|l|l|}
    \hline
    % after \\: \hline or \cline{col1-col2} \cline{col3-col4} ...
    \textbf{C1} & \textbf{C2} & \textbf{C3} & \textbf{C4} & \textbf{C5} \\ \hline
    R11 & R21 & R31 & R41 & R51 \\
    R12 & R22 & R32 & R42 & R52 \\ \cline{1-1}
    R13 & R23 & R33 & R43 & R53 \\  \cline{4-4}
