It seems that tabular is not an environment supported by MathJax, as can be seen here. So, a possible solution is to convert the tabular environment to array. Assuming that all the cells are in math mode, this can be done by the function to_array defined as follows:

def to_array(tabular):
return tabular.replace("tabular","array").replace("$","").replace(r"\\",r"\\\\")

Note that backslashes in the \\ commands should be doubled so that Markdown can process them correctly. Let us test it using the table in the question asked here:

def to_array(tabular):
 return tabular.replace("tabular","array").replace("$","").replace(r"\\",r"\\\\")

Note that backslashes in the newline commands should be doubled so that Markdown can process them correctly. Let us test it using the table in the question asked here:

variables = flatten([[var(f"alpha_{i}_{j}", latex_name=fr"\alpha_{{{i} {j}}}") 
                    for j in [0..2]] for i in [0,1]])
table_object = table([[f(v) for v in variables] for f in [sin, cos, tan]],
               header_row=variables, header_column=[f, sin, cos, tan])
tabular_env = latex(table_object)
print(to_array(tabular_env))

Now, one can copy the output and paste it in the text box to post or answer a question:

$$\begin{array}{l|llllll} f & {\alpha_{0 0}} & {\alpha_{0 1}} & {\alpha_{0 2}} & {\alpha_{1 0}} & {\alpha_{1 1}} & {\alpha_{1 2}} \\ \hline \sin & \sin\left({\alpha_{0 0}}\right) & \sin\left({\alpha_{0 1}}\right) & \sin\left({\alpha_{0 2}}\right) & \sin\left({\alpha_{1 0}}\right) & \sin\left({\alpha_{1 1}}\right) & \sin\left({\alpha_{1 2}}\right) \\ \cos & \cos\left({\alpha_{0 0}}\right) & \cos\left({\alpha_{0 1}}\right) & \cos\left({\alpha_{0 2}}\right) & \cos\left({\alpha_{1 0}}\right) & \cos\left({\alpha_{1 1}}\right) & \cos\left({\alpha_{1 2}}\right) \\ \tan & \tan\left({\alpha_{0 0}}\right) & \tan\left({\alpha_{0 1}}\right) & \tan\left({\alpha_{0 2}}\right) & \tan\left({\alpha_{1 0}}\right) & \tan\left({\alpha_{1 1}}\right) & \tan\left({\alpha_{1 2}}\right) \\ \end{array}$$

It seems that tabular is not an environment supported by MathJax, as can be seen here. So, a possible solution is to convert the tabular environment to array. Assuming that all the cells are in math mode, this can be done by the function to_array defined as follows:

def to_array(tabular):
    return tabular.replace("tabular","array").replace("$","").replace(r"\\",r"\\\\")

                    for j in [0..2]] for i in [0,1]])
table_object = table([[f(v) for v in variables] for f in [sin, cos, tan]],
               header_row=variables, header_column=[f, header_column=[function("f"), sin, cos, tan])
tabular_env = latex(table_object)
print(to_array(tabular_env))
