• Welcome! Your code has non-ASCII characters and misses quite a few $ signs to switch to math mode. – user194703 Apr 2, 2020 at 4:44 • @Schrödinger'scat Yeah just noticed it. Check the edited one Apr 2, 2020 at 4:46 ## 1 Answer Well, to zeroth approximation you could do the following. \documentclass{article} \usepackage{booktabs} \usepackage[margin=0.5in]{geometry} \begin{document} \begin{table}[h] \centering \caption{Mean of MSEs for training set for Example 1.} \label{tab:table1} \begin{tabular}{c c c c} \toprule Step size &\multicolumn{3}{c}{Number of iteration}\\ \cmidrule{2-4} (h)&1000 & 3000 &5000\\ \midrule 0.1 &$1.574 \times 10^{-5} \pm 3.879 \times 10^{-5}$&$1.498 \times 10^{-6} \pm 1.498 \times 10^{-6}$&$5.191 \times 10^{-5} \pm 1.596 \times 10^{-4}\$\\

However, every real solution will require you to upload a minimal working example that shows other what your document looks like (page geometry, document class, font size). That is, you may want to upload a minimal document like the above but with your settings.
