Do you want the timetable to look like that or do you want the data out of the cell arrays and vertically concatenated? That is, do you want a table (or maybe timetable) that's 1064 rows tall instead of 8? If so, you'll probably want to undo whatever you're doing that's wrapping the columns in cells. If that's not an option, the data in the state it's shown above can't really expand them all in one step, although it can be done by iterating over the variables using varfun:
>> t
t =
2×2 table
Var1 Var2
____________ ____________
{3×1 double} {3×1 double}
{2×1 double} {2×1 double}
>> varfun(@(x) vertcat(x{:}),t)
ans =
5×2 table
Fun_Var1 Fun_Var2
________ ________
1 6
2 7
3 8
4 9
5 10
