Super Table give you more control and options over repeatable content in Craft CMS, featuring 3 different field layouts, each addressing specific needs. Which layout you choose will depend on what sort of fields you have in your Super Table, and the number of fields.
Looking just like a native Table field, the table layout has a simple goal – to allow all fields to be used in columns.Table fields only allow plain-text columns, but with Super Table, you can add Assets, Dropdown, Entries, and any third-party field to columns.
A table layout works best for a small number of columns, due to a limited horizontal space. For more fields, you would best opt for the row layout.
The row layout acts in a similar fashion to a Matrix field, with field labels in-line with fields. This provides a more concise and space efficient layout, particularly with large Matrix fields.
The row layout also shines brightest when used inside a Matrix field.
Sometimes its useful to visually group certain fields together, and in turn make them appear more compact. The static option can be turned on to change the field into a non-repeatable collection of fields.
There's no current way to natively have nested Matrix fields in Craft CMS, and sometimes the situation calls for it.
For example – a Matrix block for a section on a page with a heading, excerpt and a slider. The slider field needs to have multiple slides consisting of an image, heading and button. In this scenario, you need to have repeatable Matrix blocks, with repeatable Super Table blocks inside each.
