Accessibility compliance

Hello, I use your calendar since it was a pull request on Semantic-UI repository.
I have a request for you: can you make your addon compliant with accessibility standards (WCAG 2.0)?

AChecker returns the following errors:

Check 244: Data table with both row and column headers does not use scope to identify cells.
Repair: Add scope attributes to header cells so they identify the cells that relate to the header.

Line 553, Column 237:
<table class="ui celled center aligned unstackable table seven column day"><thead><tr><th colspan="7 ...
Line 608, Column 153:
<table class="ui celled center aligned unstackable table seven column day"><thead><tr><th colspan="7 ...

Check 245: Data table with more than one row/column of headers does not use id and headers attributes to identify cells.
Repair: Add id and headers attributes to table cells so they identify the cells that relate to the headers.

Line 553, Column 237:
<table class="ui celled center aligned unstackable table seven column day"><thead><tr><th colspan="7 ...
Line 608, Column 153:
<table class="ui celled center aligned unstackable table seven column day"><thead><tr><th colspan="7 ...

Thank you.

Inspect the calendar source that generates the tables shown at lines 553 and 608, beginning with the header rows and associated cells. Verify the reported AChecker checks after adding the required table relationships; done means those two errors are resolved and the calendar remains usable with accessibility tools.
