w:noWrap (Table Cell No Content Wrap)

Prevents text from wrapping within a table cell, causing the cell to expand horizontally to fit content on a single line.

Parent elements

w:tcPr

Description

w:noWrap is a toggle element that, when set on a cell, prevents its content from wrapping to multiple lines. Instead of wrapping, the cell grows wider, which may push the table beyond its declared width.

It is defined in ECMA-376 Part 1 §17.4.31.

Attributes

Attribute	Type	Possible Values	Description
`w:val`	`ST_OnOff`	`true`, `false`, `1`, `0`, `on`, `off`	Enables or disables no-wrap. Omitting `w:val` is equivalent to `true`.

Examples

<w:tc>
  <w:tcPr>
    <w:noWrap/>
  </w:tcPr>
  <w:p><w:r><w:t>Long label that should not wrap</w:t></w:r></w:p>
</w:tc>

using DocumentFormat.OpenXml.Wordprocessing;

var tcPr = new TableCellProperties(
    new NoWrap()
);

Notes

w:noWrap interacts with w:tblLayout: in a fixed-layout table, the cell may overflow into adjacent cells or be clipped if there is no room to expand.
In autofit tables, w:noWrap reliably prevents wrapping by widening the column.
Use with caution in narrow tables — the content may overflow the page margin.
