Reviewer's Guide

This PR introduces a new FitAllColumnWidth API that invokes a JavaScript routine to auto-fit every column in the table and refines the cell width calculation to account for border sizes.

**suggestion:** Adding a hardcoded '+ 1' to width calculation may introduce inconsistencies.

This change may cause off-by-one errors or misalignment. If it's addressing a specific rendering issue, please document the rationale or explore a more reliable fix.

```suggestion
    // Removed hardcoded '+ 1' to avoid off-by-one errors. If subpixel rendering causes issues, consider using Math.ceil().
    const width = Math.ceil(
        div.offsetWidth +
        parseFloat(cellStyle.getPropertyValue('padding-left')) +
        parseFloat(cellStyle.getPropertyValue('padding-right')) +
        parseFloat(cellStyle.getPropertyValue('border-left-width')) +
        parseFloat(cellStyle.getPropertyValue('border-right-width'))
    );
    return width;
```

**suggestion (code-quality):** Inline variable that is immediately returned ([`inline-immediately-returned-variable`](https://docs.sourcery.ai/Reference/Rules-and-In-Line-Suggestions/JavaScript/Default-Rules/inline-immediately-returned-variable))

```suggestion
    return div.offsetWidth + parseFloat(cellStyle.getPropertyValue('padding-left')) + parseFloat(cellStyle.getPropertyValue('padding-right')) + parseFloat(cellStyle.getPropertyValue('border-left-width')) + parseFloat(cellStyle.getPropertyValue('border-right-width')) + 1;

```

<br/><details><summary>Explanation</summary>Something that we often see in people's code is assigning to a result variable
and then immediately returning it.

Returning the result directly shortens the code and removes an unnecessary
variable, reducing the mental load of reading the function.

Where intermediate variables can be useful is if they then get used as a
parameter or a condition, and the name can act like a comment on what the
variable represents. In the case where you're returning it from a function, the
function name is there to tell you what the result is, so the variable name
is unnecessary.
