narrow plugin
Applies to: ✅ Microsoft Fabric ✅ Azure Data Explorer
The narrow plugin "unpivots" a wide table into a table with three columns:
- Row number
- Column type
- Column value (as
string)
The narrow plugin is designed mainly for display purposes, as it allows wide
tables to be displayed comfortably without the need of horizontal scrolling.
The plugin is invoked with the evaluate operator.
Syntax
T | evaluate narrow()

Examples
The following example shows an easy way to read the output of the Kusto
.show diagnostics management command.
.show diagnostics
| evaluate narrow()
The results of .show diagnostics itself is a table with a single row and
33 columns. By using the narrow plugin we "rotate" the output to something
like this:
