Make Variable Names in a table numbers

I have a table that needs to have the variable names (columns) as numbers. When I try to assign the variablenames to the table t, i get this error. It is an array of 800 numbers that each have to be assigned a column. How do I make this work? Is there a way I can use array2table and specify the first row of numbers as the header? That is what I am trying to do below but it is not working.

t = array2table(allDataT(2:26,:)) %converting allDataT from rows 2 to 26 to a talbe
t.Properties.VariableNames = (allData(1,:)) % Trying to specify that the first row of numbers should be the header
% ERROR: The VariableNames property is a cell array of character vectors. 
% To assign multiple variable names, specify nonempty names in a string arrayor a cell array of character vectors.

Header are strings, not numbers. You cannot use numbers to be a header.

allData = reshape(1:64, 8, 8)

allData = 8×8

1 9 17 25 33 41 49 57 2 10 18 26 34 42 50 58 3 11 19 27 35 43 51 59 4 12 20 28 36 44 52 60 5 13 21 29 37 45 53 61 6 14 22 30 38 46 54 62 7 15 23 31 39 47 55 63 8 16 24 32 40 48 56 64

t = array2table(allData);
t.Properties.VariableNames = string(allData(1,:))

t = 8×8 table
    1    9     17    25    33    41    49    57
    _    __    __    __    __    __    __    __

    1     9    17    25    33    41    49    57
    2    10    18    26    34    42    50    58
    3    11    19    27    35    43    51    59
    4    12    20    28    36    44    52    60
    5    13    21    29    37    45    53    61
    6    14    22    30    38    46    54    62
    7    15    23    31    39    47    55    63
    8    16    24    32    40    48    56    64

Instead of 1,9, ... you have the headers "1", "9", ...
