多行表格标题无法水平居中

我编写了如下所示的表格，但无论我尝试什么选项，表格的标题都会右对齐，并且不会以粗体显示。我该怎么做才能纠正这个问题？

\begin{table}[h]
\centering
\begin{tabularx}{\linewidth}{llX} 
\toprule
\multicolumn{3}{l}\textbf{Adapterfinder.py Output File Structure.} \\
\hline
\textbf{File Line} & \textbf{Element} & \textbf{Example} \\
\hline
Meta line 1 & Parent filename & ``Report generated from input\_filename.FASTQ'' \\
\hline
Meta line 2 & Adapter sequence used & ``Adapter sequence: AGATCG'' \\
\hline
Line 1 & Read ID & ``@HWI-3:1101:1239:1968'' \\
\hline
Line 2 & Read sequence & ``TNGCNTAGNGGATTGCATGCAGA'' \\
\hline
Line 3 & Adapter sequence found & ``Adapter contamination: AGA'' \\
\bottomrule
\end{tabularx}
\end{table}
