Expanded Tables mode temporarily adds cell padding and spacing to all tables in a document and increases the tables’ borders to make editing easier. This mode enables you to select items in tables or precisely place the insertion point.
For example, you might expand a table to place the insertion point to the left or right of an image, without inadvertently selecting the image or table cell.
Select View > Table Mode > Expanded Tables Mode.
In the Layout category of the Insert bar, click Expanded Tables Mode.
A bar labeled Expanded Tables Mode appears across the top of the Document window. Dreamweaver adds cell padding and spacing to all tables on the page and increases the tables’ borders.
