Is it possible to insert multidimensional arrays within table entries?

For example: I want to create a table with 5 rows and 2 columns. The first column is just 5 rows of doubles. Can I insert a 3x3x2 array into every row of the second column?

It is possible, but technically it's a 1x1 cell array which contains the 3x3x2 double array -
data1 = rand(5, 1);
data2 = repmat({rand(3,3,2)}, 5, 1);
y=table(data1, data2)
y = 5×2 table
data1 data2 ________ ______________ 0.67046 {3×3×2 double} 0.30826 {3×3×2 double} 0.65208 {3×3×2 double} 0.8973 {3×3×2 double} 0.046877 {3×3×2 double}

I don't think an element of table can be a mutli-dimensional array, but it can be a cell that holds a multidimensional array:
% Create a cell array that will be converted to a table
c = {1,rand(3,3,2);
2,rand(3,3,2);
3,rand(3,3,2);
4,rand(3,3,2);
5,rand(3,3,2)
};
% Convert to table
t = cell2table(c)
t = 5×2 table
c1 c2 __ ______________ 1 {3×3×2 double} 2 {3×3×2 double} 3 {3×3×2 double} 4 {3×3×2 double} 5 {3×3×2 double}
% Contents of t(1,2) is a cell array
t{1,2}
ans = 1×1 cell array
{3×3×2 double}
% Contents of that cell is the 3,3,2 array
t{1,2}{:}
ans =
ans(:,:,1) = 0.0665 0.1908 0.2427 0.5777 0.5714 0.0996 0.8492 0.3431 0.9827 ans(:,:,2) = 0.2977 0.2038 0.3317 0.9687 0.0533 0.0859 0.9267 0.6033 0.2975
I'm therefore not sure if a table would be the most appropriate way to store these data, as opposed to a cell array directly.
(But, I could be wrong about a more direct way to store the array.)
