2.1.558 Part 1 Section 17.18.93, ST_TextDirection (Text Flow Direction)
a. The standard states that tbLrV orients lines from top to bottom, left to right and tbRlV orients lines from top to bottom, right to left.
The standard states:
|
Enumeration Value |
Description |
|---|---|
|
btLr (Lines Flow From Left to Right) |
Semantically equivalent to lr. |
|
lrTb (Lines Flow From Top to Bottom) |
Semantically equivalent to tb. |
|
lrTbV (Lines Flow From Top to Bottom, Rotated) |
Semantically equivalent to tbV. |
|
tbLrV (Lines Flow From Left to Right, Rotated) |
Semantically equivalent to lrV. |
|
tbRl (Lines Flow From Right to Left) |
Semantically equivalent to rl. |
|
tbRlV (Lines Flow From Left to Right, Rotated) |
Semantically equivalent to lrV. |
In Word, these enumeration values have different meanings when used in the context of a table.
|
Enumeration Value |
Description |
|---|---|
|
btLr (Bottom to Top, Left to Right) |
Specifies that text in the parent object shall flow from bottom to top vertically, then from left to right horizontally on the page.
This means that vertical lines are filled before the text expands horizontally. |
|
lrTb (Left to Right, Top to Bottom) |
Specifies that text in the parent object shall flow from left to right horizontally, then top to bottom vertically on the page.
This means that horizontal lines are filled before the text expands vertically. |
|
lrTbV (Left to Right, Top to Bottom Rotated) |
Specifies that text in the parent object shall flow from left to right horizontally, then top to bottom vertically on the page.
This means that horizontal lines are filled before the text expands vertically.
This flow is also rotated such that any East Asian text shall be rotated 270 degrees when displayed on a page. |
|
tbLrV (Top to Bottom, Left to Right Rotated) |
Specifies that text in the parent object shall flow from top to bottom vertically, then left to right horizontally on the page.
This means that vertical lines are filled before the text expands horizontally.
This flow is also rotated such that all text is rotated 90 degrees when displayed on a page. |
|
tbRl (Top to Bottom, Right to Left) |
Specifies that text in the parent object shall flow from right to left horizontally, then top to bottom vertically on the page.
This means that horizontal lines are filled before the text expands vertically. |
|
tbRlV (Top to Bottom, Left to Right Rotated) |
Specifies that text in the parent object shall flow from top to bottom vertically, then left to right horizontally on the page.
This means that vertical lines are filled before the text expands horizontally.
This flow is also rotated such that all text is rotated 90 degrees when displayed on a page. |
b. The standard states that btLr enumeration value was removed from the ST_TextDirection simple type.
-
Word does not respect this value when used at the section level.
c. The standard states that rlV orients the text from top to bottom, then right to left, rotated.
-
Word does not respect this value when used at the section level.
d. The standard states that lrV orients the text from top to bottom, then left to right, rotated.
-
Word does not respect this value when used at the section level.
