How to set the height of TD in table to 1px

When creating EDM, you will encounter the need to set the TD height to 1px. If the TD label has & nbsp;, no matter how you set the TD height, it will be useless. The minimum height is 18px,

Remove & nbsp; from the table. Example:

It turns out to be like this:

<Tr>
<TD width = "20" Height = "1"> & nbsp; </TD>
<TD width = "607"> & nbsp; </TD>
<TD width = "20"> & nbsp; </TD>
</Tr>

You need to change it to the following:

<Tr>
<TD width = "20" Height = "1"> </TD>
<TD width = "607"> </TD>
<TD width = "20"> </TD>
</Tr>

Remove & nbsp; from td to solve the problem.
