Sphinx Latex在数组中使用cline

如何解决Sphinx Latex在数组中使用cline

我正在使用Sphinx（v3.2.1）和Latex生成矩阵方程，我想对数组使用cline，但是它不会按预期方式呈现：

.. math::
  :label: lp

  \left[
  \begin{array}{cc|c}
    a_{11} &a_{12} &b_1 \\
    a_{21} &a_{22} &b_2 \\
    a_{31} &a_{32} &b_3 \\ \cline{1-2}
    c_{1}  &c_{2}  &d \\
  \end{array}
  \right]

解决方法

所以我偶然发现了这个问题，因为我有一个非常相似的问题。我不确定您是否确实设法解决了它，因为它是不久前解决的，但这是我的工作：我只是使用了 \hline 而不是 \cline。

.. math::

  \left[
  \begin{array}{cc|c}
    a_{11} &a_{12} &b_1 \\
    a_{21} &a_{22} &b_2 \\
    a_{31} &a_{32} &b_3 \\ 
    \hline
    c_{1}  &c_{2}  &d \\
  \end{array}
  \right]
