Try the following solutions:
Check to see if the Click and Type feature is turned on
Enable the Click and Type pointer
In the document, point to a blank area, and then click to enable the Click and Type pointer (Click and Type pointer shapes: Indicate which formatting will be applied when you double-click: a left-aligned, centered, or right-aligned tab stop; a left indent; or left or right text wrapping.). As you move the Click and Type pointer, the pointer shape indicates how an item will be formatted. For example, if you point to the center of the page, the pointer shape indicates that the item will be centered.
Double-click in the document
If you click once, Click and Type won't move the insertion point to the location you specified.
Work in either print layout view or Web layout view
Click and Type is not available in the following views: normal view (normal view: A view that shows text formatting and a simplified page layout. Normal view is convenient for most editing and formatting tasks.), outline view (outline view: A view that shows the headings of a document indented to represent their level in the document's structure. You can also use outline view to work with master documents.), and print preview (print preview: A view of a document as it will appear when you print it.).
Insert items only in blank areas where Click and Type is available
Click and Type isn't available in the following areas: multiple columns, bulleted and numbered lists, next to floating objects (floating object: A graphic or other object that is inserted in the drawing layer so that you can position it precisely on the page or in front of or behind text or other objects.), to the left or right of pictures with top and bottom text wrapping, or to the left or right of indents.
Use the Draw Table tool to create side-by-side tables
You can't use Click and Type to insert a table beside an existing table.
