How do I fix Invalid use of operator in the Code

I want to create a datetime table from excel having date and time in two separate columns.

T = readtable('LP.xlsx');
Col2 = datetime(str2double(T{:,2}), 'ConvertFrom','excel', 'Format','HH:mm:ss');   % Dates
Col1 = datetime(str2double({:,1}),'ConvertFrom','excel', 'Format','dd/MM/yyyy');   % Times

Invalid use of operator.

DT = table(Col1+timeofday(Col2), 'VariableNames',{'DateTime'});                 % Combined
T = [DT T(:,3:end)];                                                            % New Table
FirstFiveRows = T(1:5,:)

Error using datetime
Invalid parameter name: ConverFrom.

Please How do I merge column 1(Date) and column 2(Time) to one column having datetime? Thanks
