How to create an empty table of size with headers in Matlab

Question

I would like to create a table of 5 columns and 10000 rows, such that it has headers with empty cells in the beginning. I will fill in the cells with strings or numbers later after calculation. How to do that? Thanks.

Here is a way:

Let's say you have the following headers:

headers = {'A' 'B' 'C' 'D' 'E'};

Then initialize the data (in your case 10 000 x 5, here 4 x 5) as an empty cell. Then convert to a table and edit the VariableNames property to make it the headers:

data = cell(4,5);
T = cell2table(data);
T.Properties.VariableNames = headers

Output:

T = 

    A     B     C     D     E 
    __    __    __    __    __

    []    []    []    []    []
    []    []    []    []    []
    []    []    []    []    []
    []    []    []    []    []
