Bharath has made a table of content for his document, in which he wants to make few changes, but he is unable to make the changes. Give reason. Explain how he can make the necessary changes.

Explanation:

Microsoft Word has an automatic table of contents function that can automatically generate a table of contents for your document, provided you correctly tag the chapter headers and sub-headers that you wish to show in your table of contents.  Setting this up can be a time-consuming process, but if you are writing a lengthy document that will go through several drafts, the automatic Table of Contents can save you a lot of manual revising each time your page numbers or chapter titles change.

Step 1:  In order for Word to identify the headers and subheaders for your Table of Contents, you need to apply the appropriate "Heading" styles to your chapter and sub-chapter headers.

For example, to mark a chapter title as a Level 1 Heading, first select the text that you would like to appear as the chapter heading in the Table of Contents by clicking-and-dragging your cursor over it to highlight it.
