Correct Bracket Usage

[owneyjs15]

Would someone be able to explain the correct usage of brackets in M. Particularly i'm trying to understand why this statement:

Html.Table(_, {"Style Number", ".style-number > SPAN:nth-child(1):nth-last-child(1)"})

fails but this one works:

Html.Table(_, {{"Style Number", ".style-number > SPAN:nth-child(1):nth-last-child(1)"}})

 (The second one has double curly brackets while the first has only one). I understand that they are used to define a list. Is it just that the Html.Table function requires a list of list to work properly?

Hi @owneyjs15 

This documentation and the example in it should give you more understanding of how the function works.
