27.3.10 Using span IDs with row or column IDs

When ColIDs=Yes:

• If ColSpanIDs=No, Mif2Go interprets horizontally straddled cells in a column-header row as applying to all the body cells below them. For example, if the first cell in column 2 also straddles the cell next to it in column 3, Mif2Go generates headers="col2" for the body cells in columns 2 and 3.
• If ColSpanIDs=Yes, the cells are identified as follows:
• The straddling cell gets id="spann" instead of id="col2".
• The two non-straddling cells in the first row below the straddling cell get id="col2" (left cell) and id="col3" (right cell).
• The rest of the non-straddling cells below get headers="col2" (left column) and headers="col3" (right column).
• All cells below the straddling cell get headers="spann".

When RowIDs=Yes:

• If RowSpanIDs=No, Mif2Go interprets vertically straddled cells in a row-header column as applying to all the body cells to the right of them. For example, if the first cell in row 2 also straddles the cell below it in row 3, Mif2Go generates headers="row2" for the body cells in rows 2 and 3.
• If RowSpanIDs=Yes, the cells are identified as follows:
• The straddling cell gets id="spann" instead of id="row2".
• The two non-straddling cells in the first column to the right of the straddling cell get id="row2" (top cell) and id="row3" (bottom cell).
• The rest of the non-straddling cells to the right get headers="row2" (top row) and headers="row3" (bottom row).
• All cells to the right of the straddling cell get headers="spann".
