If you specify table border, cellspacing, or cellpadding values in the [Attributes] section, Mif2Go also includes the Border, Spacing, and Padding settings in the [Tables] section, resulting in duplicate assignments, which are not valid HTML. For these attributes, use only the [Tables] section.
If you specify border, cellspacing, or cellpadding values for a table or group of tables in [TableAttributes], even if what you list in [TableAttributes] does not include any corresponding attributes, for that group of tables Mif2Go ignores all of the following:
This means that if you set any of border, cellspacing, or cellpadding in the [TableAttributes]section, you must set them all; the entry in [TableAttributes] replaces all three. If you set border="0" and you want any cell padding or cell spacing, in the same [TableAttributes] entry you must specify greater-than-zero values for cellspacing and cellpadding. If you omit an attribute, Mif2Go writes no value at all for that attribute, in which case the browser default would apply.
