Problem css borders

Hi there,

I have a problem with the css of a table.

When I import a table created with your plugin in a category page, like this one for example: https://nnhotempo.it/cucina/pentola-pressione-elettrica/#1.2.1 (scroll down until you find the first table) the borders are not there.

If I import the same table in a post page, the borders are always displayed.

Can you help me to find the issue? Thanks
