That is the context I am most interested in. If ...


Clear["Global`*"] TableForm should only be used for display. Assign a name to the input to TableForm and take the column that you want from the input. SeedRandom[1234]; (mat = RandomReal[1, {9, 3}]) // TableForm For the second column mat[[All, 2]] {* {0.521964, 0.0116446, 0.479332, 0.984993, 0.884729, 0.91956, 0.587943, \ 0.696159, 0.632741} *} ...
