# Landscape table and notes

Two questions

1. I have seven tables, two of them should be landscape instead of portrait. How do I make the landscape ones? What do I need to change/add to the below for the landscape tables?

2. I am trying to make the tables centered and the notes at the end not-centered. How do you do that?

\documentclass[10pt]{article}
\usepackage {graphicx}
\usepackage{caption}
\usepackage{booktabs}
\usepackage[margin=0.8in]{geometry}
\usepackage[T1]{fontenc}
\begin{document}

%table 1
\begin{table}[htbp]
\begin{threeparttable}
\centering
\caption{}
\begin{tabular}{rrrrrr}

\end{tabular}%
\begin{tablenotes}
\small
\item Notes:
\end{tablenotes}
\end{threeparttable}
\label{tab:addlabel}%
\end{table}%
\end{document}
