Description  & The user shall be able to scroll through the list of entries in the database\\
\hline
Rationale&  The client identified a similar app that had scrolling behavior in and alphabetical list and really liked the way the app worked.  As users will generally know how to spell the scale name, this is a natural way to access the scales as well as browse available scales\\

Answer 1

一个空白行开始一个新段落，该段落会缩进。默认情况下，节标题后面的段落不会缩进。因此，您需要防止后续表格缩进以确保垂直对齐：

\documentclass{article}
\usepackage[table]{xcolor}
\begin{document}
