It seems a recent update to Discourse changed the CSS for tables somehow (adding a border?) and I ended up with horizontal white lines going across my custom header which relied on a vanilla HTML table for some custom text layout.

The solution was to give the rows of the table a custom class (‘my-header-row’) and then the following CSS got rid of the lines:

.my-header-row {
border:0px;
}
