PHP Information was not being displayed properly under Tech Support

[YongBoLiu]

Describe the bug

A clear and concise description of what the bug is.

A theme has a feature, mouse over event added for all table rows even the rows are not select-able.
As the php info has many rows in one form_alternate_row() call, the page looks ugly when mouse over it.
form_alternate_row() in here is misleading to other themes to deal with odd, even, tableRow class.

To Reproduce

Steps to reproduce the behavior:

1. Add a new theme like spectrum for highlight-able even the rows are not select-able.

2. Go to Utilities- System Utilities - technich support-php info page.

3. The page looks ugly when mouse over it.

Expected behavior

A clear and concise description of what you expected to happen.

We should not use form_alternate_row() for one row with many rows' content.
