Pull Request

🤨 Rationale

This is part of #1011

This PR adds the initial implementation of the nimble-table-column-number-text with configuration to render the number using a default formatter or as an integer.

There are a number of additional configurations that still need to be added to the column, such as:

• Text alignment (right vs left)
• Additional formatting options (decimal and custom)
• Prefix & suffix
• Locale-aware formatting

👩‍💻 Implementation

The new column follows the same patterns as other table columns in nimble and uses the existing TableColumnTextCellViewBase and TableColumnTextGroupHeaderViewBase.

More interesting/complex implementation will come in future PRs.

🧪 Testing

• New unit tests
• New storybook page (manually tested)
• New matrix tests

✅ Checklist

• I have updated the project documentation to reflect my changes or determined no changes are needed.

Moving this PR back to draft to address some formatting changes discussed in person:

• Use 6 digits of precision
• Remove custom E -> e+ formatting
• Don't set useGrouping: false

I will also update the HLD to reflect these changes.
