我有需要放入论文中的数据表，它们必须处于横向模式，因为有更多的列并且所有工作表中的标题必须相同。背面的编译时间过长。我也在使用该包threeparttable，因为我想使用表格注释在表格末尾发表评论。使用的 MWE 如下所示。我想知道我使用的方法是否正确。或者有更好的方法吗？

\textbf{Note:}\\
Dates of Observation correspond to the continuum flux minima and flux maxima.
Continuum and emission-line fluxes - minima, maxima and average are in units of 10$^{-14}$ erg/s/cm$^2$/\AA \space and 10$^{-13}$ erg/s/cm$^2$/\AA \space respectively.
N is the number of epochs of observations considered for computing mean continuum and emission-line fluxes and its error. F$_{Var}$ is in percentage.
