e.g.
plt = fit model(<params>); rpt = plt << report; rpt(TableBox[7]) << make data table();
but the trouble is if JMP changes or a singularity occurs TableBox[7] changes identity and is no longer the tablebox I'm after for a data table, would prefer e.g.
crossvalidation_table = rpt(TableBox["Crossvalidation"]) << make data table();
-- if I'm not mistaken, directly assigning the table to a variable as in the e.g. is also a new feature request.
