I am trying to alter the looks of a TOC in an existing document by the
following steps:
1) Right-click on TOC and select "Edit Field".
2) With field name "TOC", click on "Table of Contents..." button.
3) Select "......." from the dropdown list box of Tab Leader, which can be
found below the checkbox for "Right align page number" item.
4) Click on OK button.
The selected Tab Leader is not reflected in the TOC after it is "updated".
