one column in to multiple column

I have a .mat data file (results.mat). The first five columns are the date and time like yyyy, mm,dd,mm.
The 12th column has the data I need Results(:,12).
I wanted to use date (dt4) to split the column in to multiple columns:
dt4 =datetime(Results(:,1),Results(:,2), Results(:,3),0,0,0);
I tried to use
newtable = reshape(Results(:,12), 157, []);
then I realized that some days have different amount of data.
I want the date as column name. Could you kindly help me? I am new to MATLAB.

You forgot to attach results.mat!
If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

It's not possible to have a table with different number or rows by variable(column); MATLAB is NOT a spreadsheet (which is agoodthing™).
It is also generally better to keep data as fields and use the field values as grouping or selection variables than to break up into different variables and then have to try to recombine to do something with.
Attach the data as a .mat file and describe what you're trying to accomplish and somebody's bound to have a way to approach it "the MATLAB way".
