If you just use perspective (which this library uses for grid views), support for dataframes is native.

What are dataframes?

Think of dataframes (from Pandas library) as excel tables on steroids.

Underneath dataframes are a collection of Numpy arrays with ton of extra methods on top.

they're basically tabular data where columns are homogenous in datatype, and where you can have different datatypes among the different columns. The rows are the data points or samples. They're very often thought of as lists of multidimensional data where the dimensions correspond to the columns, and the rows to the samples of the data.

Essentially an optimized array with lots of built in subroutines for statistical and numerical analysis.
