I want to go on writing in the first array but in a new line. The command \\ is not working for this. Can anybody help me please?
My code is:
\documentclass{article}
\usepackage[landscape]{geometry}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[ngerman]{babel}
\usepackage{multirow}
\begin{document}
\small
\begin{tabular}{|c|c|c|c|}
\hline
\multirow{2}{*} & \multicolumn{3}{c|}{Disability} \\ \cline{2-4}
& Regulatory Framework & Coverage & Qualifying Conditions \\ \hline
United States & \textbf{Social Security Act 1935} & xx & xx \\ \hline
Germany & xx & xx & xx \\ \hline
France & xx & xx & xx \\ \hline
United Kingdom & xx & xx & xx \\ \hline
\end{tabular}
\end{document}
EDIT An image to make it clearer how the table should look like.
