\newline

In ordinary text, this ends a line in a way that does not right-justify the line, so the prior text is not stretched. That is, in paragraph mode (see Modes), the \newline command is equivalent to double-backslash (see \\). This command is fragile (see \protect).

However, the two commands are different inside a tabular or array environment. In a column with a specifier producing a paragraph box such as typically p{...}, \newline will insert a line end inside of the column; that is, it does not break the entire tabular row. To break the entire row use \\ or its equivalent \tabularnewline.

This will print ‘Name:’ and ‘Address:’ as two lines in a single cell of the table.

\begin{tabular}{p{1in}{\hspace{2in}}p{1in}}
  Name: \newline Address: &Date: \\ \hline
\end{tabular}

The ‘Date:’ will be baseline-aligned with ‘Name:’.
