Hi there,
HTML tables should be used for tabular data. They weren’t designed for displaying content, although that’s mainly what they used to be used for.
Instead, I would suggest using a plugin like this: https://wordpress.org/plugins/lightweight-grid-columns/
However, you can fix this issue by adding this little bit of CSS:
table img {
max-width: initial;
}
Adding CSS: https://wordpress.org/plugins/simple-css/
Let me know if you need more info ๐
