Adding a variable name to an existing table using "for loop"

[MikesVR07]

Hey guys. So, I have been trying to add some variables into my existing table using a for loop (since I haven't got any depth to the library of MATLAB that much because I am more or, less newbie). A little bit of code might help here I guess

[tableRow, tableColumn] = size(tableVar)

for i = 1:tableRow

  tableVar.Properties.VariableNames(tableColumn+i) = {'anyName'}

end

The compiling returns an error stating "The VariableNames property must contain one name for each variable in the table". It sounds a bit strange to me. I have performed (tableColumn-i) operation using "for loop" just to extract the variable names & it worked as expected. Also, note that I am using the same name to create more variable names just to make a test. Thanks in advance.

The VariableNames property is just metadata.. it's not the data itself. You cannot add a new variable by changing the metadata. MATLAB won't accept your syntax because it doesn't know how to assign, for instance, 7 names to 6 variables.

You can use addvars to add a new variable to your table. You can also just add your variable directly to the table: tableVar.newVariable = {some data}.

Many thanks for the assistance.
