Rules that describe the data in htmx

The outliers, found in the data, beside a threshold you typed

when: { op: 'outlier' }

This grid highlights the outliers found in the data itself, shown beside a fixed threshold you typed, so you can compare the two. It lets a rule describe the shape of the data rather than a hard-coded cutoff, so unusual values surface even when you did not know the number in advance.

Building…

Loading a live grid…

This is the htmx version. A server-rendered table is upgraded in place, so the page is readable before any script runs and gains the full grid when the module loads, which suits a progressively enhanced app.

The configuration

<!-- A real, server-rendered table: readable with JavaScript off. data-field on
     each header names the column that cell becomes, and data-id on each row is
     the key the grid carries it under. -->
