Create a new table variable called Name. When you create the variable, the table modifies its first
dimension name to prevent a conflict. The updated dimension name becomes Name_1.
T{:,'Name'} = {'Martin'; 'Chester'; 'Millard'; 'James'; 'James'}
Warning: DimensionNames property was modified to avoid conflicting dimension and variable names:
'Name'. See Compatibility Considerations for Using Tables for more details. This will become an
error in a future release.

Similarly, if you assign a dimension name that is not a valid MATLAB identifier, the name is modified.
T.Properties.DimensionNames{1} = 'Last Name';

Warning: DimensionNames property was modified to make the name 'Last Name' a valid MATLAB
identifier. See Compatibility Considerations for Using Tables for more details. This will

In R2016b, tables raise warnings when dimension names are not valid identifiers, or conflict with
variable names or reserved names, so that you can continue to work with code and tables created
with previous releases. If you encounter these warnings, it is recommended that you update your
code to avoid them.
