Hi,

I am trying to center the below tables and equations and I can't to seem get them to work. I save these in my database and render them with katex.

My katex settings:

        const { default: renderMathInElement } = await import('katex/contrib/auto-render');

        renderMathInElement(katexRef.current, {
          delimiters: [
            { left: '$$', right: '$$', display: true },
            { left: '$', right: '$', display: false },
          ],
          throwOnError: false,
          errorCallback: (msg) => {
            setError(msg);
          },
        });
      } catch (err) {
        setError('Failed to load KaTeX renderer');
      }
    };

I thought maybe just rendering the equation like: $$\frac{x+1}{5 x^2}=\frac{k}{x}$$ would center it, but it did not.

The table summarizes the UV index value recorded by a research assistant at noon each day for 49 days.
$$
\begin{array}{|c|c|}
\hline
\text{UV index} & \text{Number of days} \\
\hline
1 & 9 \\
\hline
2 & 15 \\
\hline
3 & 12 \\
\hline
4 & 13 \\
\hline
\end{array}
$$
According to the table, a UV index value of 1 was recorded on how many days?

$$
\begin{aligned}
mx + ky &= -83 \\
2x + ky &= 22
\end{aligned}$$
In the given system of equations, $m$ and $k$ are constants. The graphs of these equations in the $x y$ plane intersect at the point $(5, y)$. What is the value of $m$?

when i render them I get the below:
