How do I name the first column of the table? I am able to name the other columns, but not the column that was not included in the 6x6 table. I want to name the first column Property. (in matlab R2019)

Property = {'Salinity','Oxygen','Nitrate','Silicate','Temperature','Phosphate'}

T = array2table(coeff,'VariableNames', {'Mode_1','Mode_2','Mode_3','Mode_4','Mode_5','Mode_6'},...

'RowNames', Property);

The code you posted produces an acceptable table object.

I am not certain what you want. I am guessing here:

coeff = rand(6);
Property = table({'Salinity','Oxygen','Nitrate','Silicate','Temperature','Phosphate'}','VariableNames',{' '});
T = array2table(coeff,'VariableNames', {'Mode_1','Mode_2','Mode_3','Mode_4','Mode_5','Mode_6'})
T = addvars(T, Property, 'Before','Mode_1')

producing:

T =
  6×7 table
       Property        Mode_1      Mode_2     Mode_3     Mode_4     Mode_5     Mode_6
