+Feature: Merge table cells
+  In order to form a table cell spanning multiple rows and/or columns
+  As a developer using python-docx
+  I need a way to merge a range of cells
+
+  @wip
+  Scenario Outline: Merge cells
+     Given a 3x3 table having only uniform cells
+      When I merge from cell <origin> to cell <other>
+      Then the row cells text is <expected-text>
+
+    Examples: Reported row cell contents
+      | origin | other | expected-text                             |
+      |    1   |   2   | 1\2 1\2 3 4 5 6 7 8 9                     |

+  Scenario Outline: Merge horizontal span with other cell
+     Given a 3x3 table having a horizontal span
+      When I merge from cell <origin> to cell <other>
+      Then the row cells text is <expected-text>
+
+    Examples: Reported row cell contents
+      | origin | other | expected-text                     |
+      |    4   |   8   | 1 2 3 4\7\8 4\7\8 6 4\7\8 4\7\8 9 |

+  Scenario Outline: Merge vertical span with other cell
+     Given a 3x3 table having a vertical span
+      When I merge from cell <origin> to cell <other>
+      Then the row cells text is <expected-text>
+
+    Examples: Reported row cell contents

+     Given a 3x3 table having <span-state>
+      When I merge from cell <origin> to cell <other>
+      Then the width of cell <merged> is <width> inches
+

+      | a vertical span    |    5   |   2   |    2   |  1.0  |
+      | a vertical span    |    5   |   7   |    5   |  2.0  |
