表格内的间距/对齐（tabularx、页眉、页脚）

表格内的间距/对齐（tabularx、页眉、页脚）

我不明白表格内部的间距（文本和图片之前）。我使用表格环境，很难删除表格开头的空格。还有一个问题，为什么命令：将偶数页码居中不起作用？ 在此处输入图片描述

这对我有用。如何使用表中的列很重要。

\newcommand{\headrulecolor}[1]{\patchcmd{\headrule}{\hrule}{\color{#1}\hrule}{}{}}
\newcommand{\footrulecolor}[1]{\patchcmd{\footrule}{\hrule}{\color{#1}\hrule}{}{}}
\definecolor{gray}{RGB}{145,145,145}
\headrulecolor{gray}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\renewcommand{\headrulewidth}{1mm}
\fancyhead[LE]
{%
    \begin{tabularx}{\textwidth}{l!{\color{gray}\vrule width 1mm}l X}    
    \includegraphics[scale=1]{ex.jpg}&\\
     \end{tabularx}%
            }
\fancyhead[RO]{%
