Content creation

Hello,

Here's an issue I'm experiencing - using Moodle 3.3.

The plugin installed just fine. I'm listing the steps that lead to a problem:

1. A few months ago I created a table that had lines between the rows. Photo attached. It is useful, but now I don't remember how I made the lines appear. For the moment, I am copying and modifying the table to make new tables. Do you know how to make the lines? 

2. Also, I wonder if it is possible to select a column, for formatting it. Only rows seem be selectable. 

3. Borders and background colors sometimes do not 'stick' after formatting. Ideas?

Thanks a lot!

Hola, una consulta, cuando instale el plugin todos los contenidos que yo cree en mi LMS serán públicos al igual que al crearlos en la página o hay alguna manera de colocarlos privados?
