使用Sphinx和Mathjax时，数组中包含\cline的错误输出

Question

我使用Sphinx (v3.2.1)和LaTeX来生成矩阵方程，我想使用带数组的\cline。然而，它不会像预期的那样呈现：

.. 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]

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。我不确定您是否从一段时间前就解决了这个问题，但这是我得到的结果:我简单地使用了\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]
