Description
for table layout legends, the repeated x (often time) in the first column is not great. instead it can be rendered as a table header at the top, in the empty top-left <th>, or using rowspan=0

Research direction
Start by locating the table-layout legend rendering in the JavaScript source and trace how the repeated x value is currently added to the first column. Define the option so the shared x value can instead appear as a caption or table header in the empty top-left cell, or via rowspan=0. Done means the selected rendering works without repeating the x value in every row.
