wBefore (Preferred Width Before Table Row)

This element specifies the preferred width for the total number of grid columns before this table row as specified in the gridAfter element (§2.4.10). This preferred width is used as part of the table layout algorithm specified by the tblLayout element (§2.4.49; §2.4.50) - full description of the algorithm in the ST_TblLayout simple type (§2.18.94).

All widths in a table are considered preferred because:

• The table must satisfy the shared columns as specified by the tblGrid element (§2.4.44)

• Two or more widths may have conflicting values for the width of the same grid column

• The table layout algorithm (§2.18.94) may require a preference to be overridden

This value is specified in the units applied via its type attribute. Any width value of type pct for this element shall be calculated relative to the text extents of the page (page width excluding margins).

If this element is omitted, then the cell width shall be of type auto.

[Example: Consider a WordprocessingML table row defined as follows:

<w:tr>
<w:trPr>
<w:gridBefore w:val="1"/>
<w:wBefore w:type="fixed" w:w="1440"/>
</w:trPr>
…
</w:tr>

This table specifies that it has a preferred table width of 1440 twentieths of a point (one inch) for the grid column before the start of the row. The resulting table would therefore be sized such that that grid column is one inch whenever possible, for example the second row in this table:

Attributes

Description

type (Table Width Type)

Specifies the units of the width property being defined by the parent element’s w attribute. This property is used to define various properties of a table, including: cell spacing, preferred width, and table margins.

If this attribute is omitted, then its value shall be assumed to be dxa (twentieths of a point).

[Example: Consider a table with a table cell bottom cell spacing with a type of dxa, as follows:

<w:bottom ... w:type="dxa" />

This type shall therefore be used to interpret the width specified in the w attribute as a value in twentieths of a point. end example]

The possible values for this attribute are defined by the ST_TblWidth simple type (§2.18.97).

w (Table Width Value)

Specifies the value of the width property being defined by the parent element. This property is used to define various properties of a table, including: cell spacing, preferred widths, and table margins.

If this attribute is omitted, then its value shall be assumed to be 0.

[Example: Consider a table with a bottom margin with a width of 302, as follows:

<w:bottom w:w="302" w:type="dxa" />

The value in the w attribute shall therefore be used to determine the width being specified in the context of the units specified in the type attribute. In this case, the type is twentieths of a point (dxa), so the width is 302 twentieths of a point (.2097 inches). end example]

The possible values for this attribute are defined by the ST_DecimalNumber simple type (§2.18.16).
