Naming Table Variables of a File

I have a table 3x1 where each value has 6 seperate values. I want to name these 6 column names. As shown in the attached screenshot, I want to name 1 for example Data1, 2 Data2 etc.

Thanks for help in advance.

load("T.mat")
T1 = splitvars(T);
T1 = renamevars(T1,["rows_1" "rows_2" "rows_3" "rows_4" "rows_5" "rows_6"],...
                   ["Data1" "Data2" "Data3" "Data4" "Data5" "Data6"])

T1 = 3×6 table
               Data1                  Data2         Data3       Data4     Data5       Data6   
    ____________________________    __________    __________    _____    _______    __________

    {'Proposed_AdaptiveMetaKNN'}    {[0.5000]}    {[0.5556]}    {[1]}    {[  1]}    {[6.4590]}
    {'Baseline_KNN_Grid'       }    {[     1]}    {[     1]}    {[5]}    {[  1]}    {[1.5000]}
    {'Baseline_SVM_Linear'     }    {[0.5000]}    {[0.3333]}    {[5]}    {[NaN]}    {[   NaN]}

Alternatively:

T2 = renamevars(T,["rows"],["Data"]);
T2 = splitvars(T2)

T2 = 3×6 table
               Data_1                 Data_2        Data_3      Data_4    Data_5       Data_6  
    ____________________________    __________    __________    ______    _______    __________

    {'Proposed_AdaptiveMetaKNN'}    {[0.5000]}    {[0.5556]}    {[1]}     {[  1]}    {[6.4590]}
    {'Baseline_KNN_Grid'       }    {[     1]}    {[     1]}    {[5]}     {[  1]}    {[1.5000]}
    {'Baseline_SVM_Linear'     }    {[0.5000]}    {[0.3333]}    {[5]}     {[NaN]}    {[   NaN]}
