/**
* A Lit directive for rendering the content of the column's body cells.
*
* The directive accepts a renderer callback returning a Lit template and assigns it to the grid column
* via the `renderer` property. The renderer is called for each column's body cell when assigned and whenever
* a single dependency or an array of dependencies changes.
* It is not guaranteed that the renderer will be called immediately (synchronously) in both cases.
*
* Dependencies can be a single value or an array of values.
* Values are checked against previous values with strict equality (`===`),
* so the check won't detect nested property changes inside objects or arrays.
* When dependencies are provided as an array, each item is checked against the previous value
* at the same index with strict equality. Nested arrays are also checked only by strict
* equality.
*
* Example of usage:
* ```js
* ` html`...`)}
* > `
* ```
*
* @param renderer the renderer callback.
* @param dependencies a single dependency or an array of dependencies
* which trigger a re-render when changed.
