Overview

Formats coverage data as a table with Unicode box-drawing or ASCII borders.

Used by CoverageModel#format_table for the default cov-loupe list output. Column widths are computed dynamically from the data. The table includes:

- File path from each row
- Coverage percentage
- Covered lines
- Total lines
- Staleness indicator

A footer row summarizes file counts (total, ok, stale).

Class Method Summary collapse
