How to program plots with models starting with table

https://www.mathworks.com/help/stats/linearmodel.plot.html provides a code example with loading dataset

load carsmall
Year = categorical(Model_Year);
tbl = table(MPG,Weight,Year);
mdl = fitlm(tbl,'MPG ~ Year + Weight^2');

But how can one program the above when one start from table T?
