If you have multiple, separate pieces of text, images, or videos you wish to feature on a page or Community, a great way to keep everything organized and formatted properly is to use a table. Here's how:
Find the page or Community you wish to edit, by going to either Publish > Pages, or Manage > Communities, respectively.
At the top of the description box, you'll see this:
2. Select the number of cells you'd like in your table, and input text and/or images as you wish.
3. Don't forget to hit save!
Please note that the table tool should be used sparingly to store pieces of information that have some kind of relation to one another. For example, if you'd like to highlight a list of upcoming presentations, perhaps in one column you include the name of a speaker, and in another column the topic being presented on.
