A hail MatrixTable is a standard data structure in hail framework. A MatrixTable consists of four components:
a two-dimensional matrix of entry fields where each entry is indexed by row key(s) and column key(s)
a corresponding rows table that stores all of the row fields that are constant for every column in the dataset
a corresponding columns table that stores all of the column fields that are constant for every row in the dataset
a set of global fields that are constant for every entry in the dataset
