Style properties defined in an element style selector are evaluated with higher priority over properties in a CSS class when importing from HTML.

For example if we have the following CSS style:

.sectionheading {
border: 10px solid red;
        }
td {
border: 10px solid black;
        }
and the class (.sectionheading) is applied on a table cell:

<td class="sectionheading">...</td>

The result in WordsProcessing after import of such HTML will be that the table cell has 10px black border. In MS Word and in the browsers (Chrome, Firefox...) the result will be that the cell has 10px red border.
