Preciso fechar a lacuna mostrada na saída:
Como modificar o MWE acima para fechar essas lacunas?
Usando TL 2019

Aqui está uma abordagem diferente usando \Xhlineo makecellpacote:
\documentclass[]{article}
\usepackage{amsmath}
\usepackage{makecell}
\begin{document}
\small
\begin{tabular}[c]{|p{1.5in}|p{4in}|}
\Xhline{0.5ex}
Problem&1\\\hline
ODE &${\frac {\rm d}{{\rm d}x}}y \left( x \right) =1+2\,x$\\\hline
ODE degree &1\\\hline
Number of solutions &1\\\hline
CAS classification &quadrature\\\hline
Program classification&{\footnotesize [separable]}\\\hline
Solved? &yes\\\hline
Verified? &yes\\
\Xhline{0.5ex}
\end{tabular}
\normalsize
\end{document}
Um exemplo usando o booktabspacote e seguindo as orientações do booktabsmanual
Você não errará muito se lembrar sempre de duas diretrizes simples: 1. Nunca, jamais, use regras verticais.
poderia ser parecido com o seguinte:
\documentclass[]{article}
\usepackage{amsmath}
\usepackage{booktabs}
\begin{document}
\begin{tabular}[c]{ll}
\midrule
Problem & 1 \\ \addlinespace
ODE &${\frac {\rm d}{{\rm d}x}}y \left( x \right) =1+2\,x$\\ \addlinespace
ODE degree &1\\ \addlinespace
Number of solutions &1\\ \addlinespace
CAS classification &quadrature\\ \addlinespace
Program classification&{\footnotesize [separable]}\\ \addlinespace
Solved? &yes\\ \addlinespace
Verified? &yes\\
\bottomrule
\end{tabular}
\end{document}
