有人能告诉我如何\raggedright在此示例中将其应用于表格标题吗？
\documentclass[a4paper,12pt]{article}
\usepackage{tabularx}
\usepackage{booktabs}
\usepackage{siunitx}
\begin{document}
\begin{table}[t]
\caption{}
\label{}
\begin{tabularx}{\textwidth}{X X X X}
\toprule
Time of induction (\SI{}{\minute}) & Mean $\text{A}_{414}$ & Corrected $\text{A}_{414}$ (minus t=0 value) & Units of $\beta$-galactosidase per \SI{}{ml} of {\it E. coli} culture\\
\midrule
0 & 0.057 & 0 & 0 \\
1 & 0.060 & 0.003 & \num{1.3e-7}\\
2 & 0.069 & 0.012 & \num{5.0e-7}\\

您可以使用它\multicolumn来覆盖原始的列规范：
\toprule
\multicolumn{1}{>{\raggedright}X}{Time of induction (\SI{}{\minute})} & \multicolumn{1}{>{\raggedright}X}{Mean $\text{A}_{414}$} & \multicolumn{1}{>{\raggedright}X}{Corrected $\text{A}_{414}$ (minus t=0 value)} & \multicolumn{1}{>{\raggedright}X}{Units of $\beta$-galactosidase per \SI{}{ml} of {\it E. coli} culture}\\
\midrule
>{decl.}直接插入decl.到列条目的前面。类似地，<{decl.}在列格式声明之后使用会decl.直接插入到列条目的后面。
