When I used the default code of MixedModels package, and a error happened that “ParseError: KaTeX parse error: No such environment: tabular at position 7: \begin{̲t̲a̲b̲u̲l̲a̲r̲}̲ {l | r | r | r…”.

The default code are below:

dyestuff = MixedModels.dataset(:dyestuff)  
fm = @formula(yield ~ 1 + (1|batch))  
fm1 = fit(MixedModel, fm, dyestuff)

I think the `tabular` environment is only available in proper LaTeX, not MathJax or KaTeX, so you’ll have to look for an alternative.

Thanks for your help, and would you please tell me that how can convert KaTex to LaTex for tabular environment.

OK, the problem has been solved when I used _println()_ function to print the fitting result. So, I thought that Katex can’t showed the MixedModel result, and we need to print it below.
