使用 multicol 包和新命令的垂直间距问题

以下代码会产生不必要的空格。为什么会产生空格？如何避免？请重新定义命令或宏。

\documentclass[letterpaper]{article}
\usepackage[dvipsnames]{xcolor}
\usepackage{enumitem,multicol,fullpage}
\usepackage{amsmath,amssymb}
\usepackage{tikz}

\newcounter{wsnumcnt}
\newcommand{\tikzmark}[1]{\tikz[overlay,remember picture] \node (#1) {};}

\usetikzlibrary{fit,positioning}
\usetikzlibrary{calc,shapes}

\newcommand{\wssectsty}[2]{%
\setcounter{wsnumcnt}{#2}%
\gdef\wssecttitle{#1}%
\section*{\tikzmark{title}\color{Orange}\wssecttitle}%
\ifnum \thewsnumcnt<10%
    \tikz[remember picture,overlay]{%
    \node [
        left=42pt of title,
        anchor=base,
        fill=Orange, 
        rectangle,
        rounded corners,

您可以将 tikz 节点移动到部分标题中，以便更好地对齐。
