Getting Error:Table variables and insert 'fieldnames' do not match. while exporting data from matlab to sql - sql

Question

I am getting the Error using database.jdbc.connection/fastinsert (line 140)
Table variables and insert 'fieldnames' do not match. error while exporting data from matlab to sql. Can you please help me out.
Below is my code.
conn = database('rScenariosDB','NCAT\aabhaler','','Vendor','Microsoft SQL Server','Server','A0030110GB6S942','AuthType','Windows','portnumber',1433);
for i = 1 : rScenarioCnt
if rScenario{i}.status == 1
ECostMax(i) = rScenario{i}.ECostMax;
CO2EmisMax(i) = rScenario{i}.CO2EmisMax;
ECost(i) = rScenario{i}.YearAlloc.ECost;
CO2Emis(i) = rScenario{i}.YearAlloc.CO2Emis ;
EmisCostYear(i) = rScenario{i}.YearAlloc.EmisCostYear ;
CO2EmisYear(i) = sum(rScenario{i}.YearAlloc.CO2EmisYear);
end
end
rId = 1 : rScenarioCnt ;
colnames={'rScenarioId' ,'ECostMax' , ' CO2EmisMax','ECost' ,'CO2Emis', 'EmisCostYear', 'CO2EmisYear' };
data = table(rId',ECostMax',CO2EmisMax',ECost',CO2Emis',EmisCostYear', CO2EmisYear','VariableNames',colnames);
tablename = 'rScenarios';
fastinsert(conn,tablename,colnames,data);
curs=exec(conn,'select * from [dbo].[rScenarios]');
curs=fetch(curs);
disp(curs.Data);
close(curs);
close(conn);
