It works in my machine to save a replay result file as table.
For the issue you mentioned, I guess the result file you are using is not the final result file, but a result file from one replay client. Before the result trace files are merged into the final one, they have an extra column in it (which is used for merging, and doesn't exist in the final merged result), and that may cause your saving_as_table fail.
If this is the reason, please use the final merged result file.
