What is '$data' in ngtable's HTML page

Question

I am using ngtable and at this place in HTML while displaying table

<tr ng-repeat="row in $data">

I do not understand the use of $data, as '$' is not needed in other cases in ng-repeat.

Answer 1

ng-table maintains it's own scope, and $data is the data which exists in this scope, rather than your full data set, which is on the scope of the page controller. It is the property that is populated by the getData() function call in the ngTableParams() object.

This usage and syntax is deprecated, and has been replaced entirely in the current ng-table source, which is now written in TypeScript as of v2.0.0.
