I'm trying to use the variable names of one of my tables in another new table, but keep getting an error saying "Error using table The VariableNames property is a cell array of character vectors. To assign multiple variable names, specify names in a string array or a cell array of character vectors" even though I have the variable names saved in a cell array. I have tried making varnames a string array, used a for loop to copy all the names to varnames, concatenated them vertically instead of horizontally just for the heck of it, but I can't seem to figure it out. This is my code:
varnames = cell.empty;
varnames = DataFinal.Properties.VariableNames
T = table('VariableNames',{varnames}, 'RowNames', {'A','B','C'})

Thanks. It seems that the use of repmat only allows one data type. I suppose that if I need to have columns of different data types, I can just change those columns after the table is created, right?

repelem({'double', 'categorical', 'double'}, 1, [17, 2, 11])
for example for the case of 17 double followed by 2 categorical followed by 11 double
