+.. _WdCellVerticalAlignment:
+
+``WD_CELL_VERTICAL_ALIGNMENT``
+==============================
+
+alias: **WD_ALIGN_VERTICAL**
+
+Specifies the vertical alignment of text in one or more cells of a table.
+
+Example::
+
+    from docx.enum.table import WD_ALIGN_VERTICAL
+
+    table = document.add_table(3, 3)
+    table.cell(0, 0).vertical_alignment = WD_ALIGN_VERTICAL.BOTTOM
+
+----
+
+TOP
+    Text is aligned to the top border of the cell.
+
+CENTER
+    Text is aligned to the center of the cell.
+
+BOTTOM
+    Text is aligned to the bottom border of the cell.
+
+BOTH
+    This is an option in the OpenXml spec, but not in Word itself. It's not
+    clear what Word behavior this setting produces. If you find out please let
+    us know and we'll update this documentation. Otherwise, probably best to
+    avoid this option.
