When importing spreadsheets containing invalid variable names, Matlab changes them and stores the original column headings in the VariableDescriptions property of the table. How can I write my table to a file and use the original variable names on export? In other words, how can I export T so that output_table.xlsx is the same as input_table.xlsx?
Reprocessing the exported file as a string is not really an option, because my original file will have multiple sheets.
T = readtable('input_table.xlsx'); % Matlab changes "Column 1" to "Column1"
writetable(T,'output_table.xlsx');

As of 2019b, table variable names don't need to follow normal variable naming rules. This allows for a couple of fixes:
T = readtable('input_table.xlsx','PreserveVariableNames',true);
or
T.Properties.VariableNames={'Column 1';'Column 2'}
