You can vertically align text inside an object: along the top, in the middle, or along the bottom.
To do this, follow these steps:
1.Select the object where you want to align the text:
•To align text within any object other than a table, select the object with a single or double click.
•To align text in a table, select it with a single click.
•To align text in one or more cells in a table, select those cells.
2.On the Home tab, in the Paragraph group, select the alignment method:
Align to top,
Align to middle or
Align to bottom. When working in macOS, you can also run the Format > Alignment > Top, Middle or Bottom command from the command menu.
If the text in a cell is rotated, vertical alignment is carried out according to its position in space: the text is moved relative to the left and right cell borders.
