disableName isn't working

[kdong007]

this is my specification

    const specification = {
        id: {
            displayName: "id",
        },
  };

but in the generated excel, i got a [object Object] as column heading.
the table contents are just fine

You need to add width (or column will be invisible) and headerStyle (there is issue with checking this prop)
