Interface DataTableBuilder

Builder of DataTable objects. Building a data table consists of first specifying its columns, and then adding its rows, one at a time. Example:

var data = Charts.newDataTable()
    .addColumn(Charts.ColumnType.STRING, "Month")
    .addColumn(Charts.ColumnType.NUMBER, "In Store")
    .addColumn(Charts.ColumnType.NUMBER, "Online")
    .addRow(["January", 10, 1])
    .addRow(["February", 12, 1])
    .addRow(["March", 20, 2])
    .addRow(["April", 25, 3])
    .addRow(["May", 30, 4])
    .build();
