在多列表格中进行 For 循环

Question

我可以不添加新行然后删除新行吗？我想跳过\\[-0.4cm]。感觉不对

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{float}
\usepackage{geometry}
\usepackage{forloop}
\usepackage{graphicx}
\geometry{a4paper, left=2.5mm, top=2.5mm,bottom=2.5mm,right=2.5mm}

\newcounter{i}
\newcommand{\mylineNewTwo}[1]{%
    \forloop{i}{0}{\value{i}<#1}%
    {%
    \\[-0.4cm]% is it possible to do this without this line??
    \multicolumn{2}{l}{Line1}\\
    \multicolumn{1}{c}{} & Line2\\
    \multicolumn{2}{l}{Line3}\\
    \multicolumn{2}{l}{Line4}\\
    \multicolumn{1}{c}{} & Line5\\
    \multicolumn{2}{l}{Line6L\hfill Line6R}\\
    }
}
