我有两个表：一个普通表和一个长表。在我的代码和引用中，普通表排在第一位，长表排在后面。但是，长表比表先出现。我该如何改变这种情况？
我希望普通桌子首先顺利出现，然后再出现长桌子。

\subsubsection{Linear variability}
Significant results obtained when testing the linear variability metrics are presented in Table \ref{table:linear_var_POAF_results}. Briefly, the variability in both time and morphological features were significantly different between POAF and controls far away from the arrhythmia (at least 18 hours away), while only variability in P-wave time features were significant as the arrhythmia onset got closer. The POAF group had higher median variability for all the presented timestamps, and showed increasing variability (slope) in all timestamps except 18 hours before the arrhythmia onset. In contrast, controls presented decreasing variability in the majority of variability regression slope results. The PQ interval (duration and level) was the only feature which had metrics significant after correction for multiple comparisons at 6 and 48 hours before the arrhythmia onset.

\subsubsection{Non-linear variability}
Non-linear CTM was found to significantly differ between POAF patients and controls in all the tested timestamps (Table \ref{table:CTM_results_POAF}). Controls were associated with higher CTM in the great majority of features and timestamps. However, CTM applied over the features P\textsubscript{vel. disp.}, P\textsubscript{fin. dur}, P\textsubscript{magn.}, PQ\textsubscript{level}, PQ\textsubscript{level Pnorm} and P\textsubscript{off amp.} was sometimes higher in POAF patients. Finally, several P-wave time- and morphological metrics were significant after correction for multiple comparisons 1, 12, 18, 42 and 48 hours before the arrhythmia onset, all of them showing higher CTM in controls.

\subsubsection{Linear variability}
Significant results obtained when testing the linear variability metrics are presented in Table \ref{table:linear_var_POAF_results}. Briefly, the variability in both time and morphological features were significantly different between POAF and controls far away from the arrhythmia (at least 18 hours away), while only variability in P-wave time features were significant as the arrhythmia onset got closer. The POAF group had higher median variability for all the presented timestamps, and showed increasing variability (slope) in all timestamps except 18 hours before the arrhythmia onset. In contrast, controls presented decreasing variability in the majority of variability regression slope results. The PQ interval (duration and level) was the only feature which had metrics significant after correction for multiple comparisons at 6 and 48 hours before the arrhythmia onset.

\subsubsection{Non-linear variability}
Non-linear CTM was found to significantly differ between POAF patients and controls in all the tested timestamps (Table \ref{table:CTM_results_POAF}). Controls were associated with higher CTM in the great majority of features and timestamps. However, CTM applied over the features P\textsubscript{vel. disp.}, P\textsubscript{fin. dur}, P\textsubscript{magn.}, PQ\textsubscript{level}, PQ\textsubscript{level Pnorm} and P\textsubscript{off amp.} was sometimes higher in POAF patients. Finally, several P-wave time- and morphological metrics were significant after correction for multiple comparisons 1, 12, 18, 42 and 48 hours before the arrhythmia onset, all of them showing higher CTM in controls.
