Hi! I want to load an unknown amount of tables, and store them in an array, list, or even a matrix.

I tried implomenting it using a simple array, and even a cell array (in which each cell represnets a table), but I always find myself getting errors like "Can't convert from table to cell".

Is there is a way to store multiple tables is some sort of a list?

Thanks in advance!

Show us what you tried so we can work out the kinks. A table can be stored in a cell array easily using

c{i} = T; % where T is a table

You can't make an "array of tables" per se, because a table is already an array. But you can put multiple tables in a cell array, as Adam shows. Another option (if they are similar enough) is to vertcat them and add a variable that says which "chunk" of data each row is from. Things like groupsummary and varfun can work with a format like that, using the new variable as a "grouping variable".
