Note: To arrange dimensions without using drag-and-drop, you can use the Rearrange report dialog. Click Table options / Chart options> Rearrange report, or else select View> Table options / Chart options> Rearrange report.
Nesting dimensions places one dimension inside another. Nesting allows a report to display more than one row or column dimension at a time. (You can also use nesting to insert a dimension on either side of a slicer dimension.)
In a table or a preview chart, you can nest dimensions by dragging and dropping them. Dimension tiles provide a textured area for dragging.
When your mouse cursor is over the textured area of a dimension tile and ready to drag it, the cursor turns into a four-pointed arrow.
A dragged tile appears as a small, empty tile. 
When the mouse cursor is placed in a nestable position at the top or bottom edge of a column dimension, or at the left or right edge of a row dimension, the image of an arrow appears in the tile. This picture shows the Time dimension ready to be dropped at the bottom edge of the Gender dimension. It will nest inside the Gender dimension on the columns.
