DataTable class

A material design data table.

Displaying data in a table is expensive, because to lay out the table all the data must be measured twice, once to negotiate the dimensions to use for each column, and once to actually lay out the table given the results of the negotiation.

For this reason, if you have a lot of data (say, more than a dozen rows with a dozen columns, though the precise limits depend on the target device), it is suggested that you use a PaginatedDataTable which automatically splits the data into multiple pages.
