table method
A table must have a name and rows. The name is necessary if you want to
read the values from it later (if not, just pass an empty string).
Example: ctx.table('notifications').row(0).val('read') as bool
.
Implementation
BddWhenTable table(String tableName, row row1,
[row? row2, row? row3, row? row4]) =>
BddWhenTable(bdd, tableName, row1, row2, row3, row4);
