Answer 1

tr = row of the table
td = table data
th = table heading
These elements create a table.

Answer 2

Hey there,

<tr> = table row:
Groups together all elements to go into a single row of the table

<th> = table header:
Holds the headline for a single column of the table. Needs to be located in between <tr>-elements. Most of the time <th>-elements go into the first row of the table, as they make up the entire headlines, as seen in your example.

<td> = table data
Holds a single data-field inside the table. Also has to go between <tr>-tags and is mostly used starting from the second row onwards.

Hope that helps a bit :-)
