UI table single quote issue (#66)

[wipfl]

• [x] Bugfix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)

Proposed changes

Issue #66 describes that a single-quote character in the description or the table name breaks the table so it is no longer rendered.

The JSON.stringify() call in function HTML has been changed so that

• all single-quote characters (') are replaced by & apos ;
• the info property is not copied to the stringified JSON.

A sample flow has been added to the example folder that tests the behaviour of the table with single and double quotes in table name, column name and description.
