If you use HTML in your assessment questions, be careful when setting up your Enterprise Reporter reports. If you check "show question wording", HTML within the body of the question will not be escaped. This means the browser tries to render it, and this can corrupt the table layout of the report.

The workaround is to display only the question descriptions, which contain no HTML, and make sure they match the actual question as closely as possible.

Shown below is part of the settings screen for a survey report showing the correct settings to use when you have included HTML within a question, particularly table-generating HTML. Note that "question description" is checked, but not question wording.
