像这样吗？

\documentclass[11pt, a4paper, svgnames]{article}
\usepackage[utf8]{inputenc}
\usepackage[brazil]{babel}
\usepackage{multirow, float}
\usepackage{diagbox}
\usepackage{pst-node, auto-pst-pdf}

\begin{document}

\begin{table}[H]
\centering\setlength\extrarowheight{3pt}
\begin{postscript}
\begin{tabular}{|c|cccc|}
\hline
\backslashbox{I5 I10}{Q1 Q0} & 00 & 01 & 11 & 10\\
\hline
00 & 0& 0 & \Rnode{T}{1} & 0\\
01 & 0& 0 & 1 & 0\\
11 & x& x & x & x\\
10 & 0& 0 & \Rnode{B}{1} & 0\\
\hline
\end{tabular}
\ncbox[linejoin =1, nodesep=0.5ex, boxsize=0.25, linecolor=IndianRed]{T}{B}

您tikz还可以选择周围边框的形状，这里有两个示例，带有ellipse和rectangle带有rounded borders。

我还冒昧地建议了另一种格式化表格的方法。

            \hline
            00 &  0& 0 & \tikzmark{fromhere}1 & 0\\
            01 &  0& 0 & 1 & 0\\

            10 &  0& 0 & \tikzmark{tohere}1 & 0\\
            \hline
        \end{tabular}
    \begin{tikzpicture}[overlay,remember picture]
            \node[ellipse, draw, blue, xshift=.27em, minimum width=1.5em,
                    fit={(pic cs:fromhere) (pic cs:tohere)}
                ] {};
    \end{tikzpicture}

            \node[rectangle, rounded corners, draw, blue, xshift=.27em, minimum width=1.5em,

第二次编辑：\tikzmark解释

使用命令\tikzmark{<my_node_name>}创建节点<my_node_name>，并将其定位到您编写此命令的位置。

随着[overlay,remember picture]你告诉你tikz，你正在创建的图片必须写在你放置的位置\tikzmark。

绘制\node[rectangle, rounded corners, draw, blue, xshift=0.27em, minimum width=1.5em, fit={($(pic cs:c44)+(-.15,.25)$)($(pic cs:c55)+(.15,-.04)$)} ] {};一个蓝色矩形，带圆角，水平移动 0.27em，最小宽度为 1.5em，必须适合以下点：

  1. 节点坐标c44水平移动 -.15cm，垂直移动 .25cm
  2. 节点坐标c55水平移动了.15cm，垂直移动了-.04cm。

\node[ellipse, draw, green, xshift=0.27em, minimum width=1.5em, fit={($(pic cs:c23)+(0,0.2)$)(pic cs:c33)} ] {};绘制一个绿色椭圆，水平移动 0.27em，与以下点相符：

  1. 节点坐标c23垂直移动.2cm
  2. 节点的坐标c33。

\draw[dashed, very thick, rounded corners, red]($(pic cs:c42)+(-.1,0.4)$) -- ($(pic cs:c42)+(.4,0.4)$) -- ($(pic cs:c52)+(.4,-.15)$) -- ($(pic cs:c52)+(-.1,-.15)$);绘制一条非常粗的红线，带有圆角，穿过以下点：

  1. 节点坐标c42水平移动 -.1cm，垂直移动 .4cm
  2. 节点坐标c42水平移动 0.4cm，垂直移动 0.4cm
  3. 节点坐标c52水平移动.4cm，垂直移动-.15cm
  4. 节点坐标c52水平移动-.1cm，垂直移动-.15cm。
