Problem description: For some reason, in Host card and Item card widget configuration forms, the "Name" header in show table is included in a "td" element instead of a "th" element, and, therefore, is formatted as plain text and not as a table header (even though all other table headers (all empty) are represented by "th" elements):

Steps to reproduce:

1. Open any dashboard in edit mode
2. Press "Add" button to add a new widget
3. Set widget type to "Host card" or "Item card"
4. Check the headers of the "Show" table.

Result: The "Name" header is formatted as text, it is represented by a "td" element on page.
Expected: The header "Name" should be formatted as a table header, like it is done, for example, in "Columns" table in Top hosts widget, or in "Items" table in Item history widget.
