How can I export the below table?

Data = load('INPUTFILEedit.mat'); 
DataName = fieldnames(Data); 
for k = 1:numel(DataName) 
ThisName = DataName{k}; 
ThisData = Data.(ThisName); 
  
tst=ThisData.Date(1:height(ThisData(2:end,2))); % just a sample set to play with 
mydates = datetime(tst,'InputFormat','yyyy-MM-dd''T''HH:mm:ss.SSSSSSSSSZ ', ... 
'TimeZone','Europe/London','Format','y-MM')

1. Use readtable to read in the data as table T.
2. Use the conversion below.
3. Write to csv using writetable

T = array2table(reshape(1:18,3,[])', 'VariableNames',{'a' 'b' 'c'},'RowNames', compose('%d',0:5))

T = 6x3 table
         a     b     c 
         __    __    __

    0     1     2     3
    1     4     5     6
    2     7     8     9
    3    10    11    12
    4    13    14    15
    5    16    17    18

T2 = array2table([reshape(T{1:3,:},1,[]); reshape(T{4:6,:},1,[])], ...
    'VariableNames', strcat(repelem(T.Properties.VariableNames,1,3), 's', compose('%d',repmat(1:3,1,3))), ...
    'RowNames', {'1','2'})

T2 = 2x9 table
         as1    as2    as3    bs1    bs2    bs3    cs1    cs2    cs3
         ___    ___    ___    ___    ___    ___    ___    ___    ___

    1     1      4      7      2      5      8      3      6      9 
    2    10     13     16     11     14     17     12     15     18
