The CSV import "Validate Data" step (step 3) renders a completely blank table because the column filtering logic in ValidationStep produces an empty columns array, causing SpreadsheetImportTable to return null.
Fix: Fixed the column filtering logic in `ValidationStep.tsx` that caused the CSV import validation table to render blank at Step 3.
**Three changes in a single `useMemo` block:**
1. **Extracted `select-row` to an early return**: The `column.key === 'select-row'` check was previously inside the `importedColumns.filter()` callback. When `importedColumns` was empty (no entries to iterate), the filter returned `[]` for ALL columns — including the row selection checkbox. Now `select-row` is handled with an early return before the `importedColumns` check, so it always renders.
2. **Replaced `.filter().length > 0` with `.some()`**: More idiomatic, more efficient (short-circuits on first match), and clearer intent.
3. **Added `'value' in importColumn` type guard**: Only compares `importColumn.value` on column types that actually have a `value` property (matched, matchedSelect, matchedSelectOptions, matchedCheckbox), safely skipping `empty` and `ignored` column types. Also restructured the boolean logic to check `value === column.key` once rather than repeating it for each type.
