This is the result that I am going for:
(The three Chinese are 调类, 调值 and 方言点.)
I just need a single td class that I can implement in my css table.
I've seen examples using pngs or other image files, but I'm not looking for an image to load each time the table is loaded.
The answer here is not bad:
Create diagonal border of a cell
but I just can't get it to do what I want!
my solution so far is just to have a single td like this:
<td>
调类 →
</br>调值 ↘
</br>方言点 ↓
</td>
looks kind of ugly though:
