…readXml() and toXml() — pd.read_xml() / DataFrame.to_xml() port Zero-dep XML tokenizer supporting attributes, child elements, CDATA, entities, namespace prefix stripping, naValues, usecols, nrows, indexCol. toXml: rootName, rowName, attribs, xmlDeclaration, namespaces, indent, cdataCols. Entity encoding/decoding, full round-trip support. 50+ tests + property tests. Playground page with 9 interactive examples.

…readTable() — pd.read_table() port Add `readTable()` function that mirrors `pandas.read_table()`: - Thin wrapper around `readCsv` defaulting sep to '\t' (tab) - Distinct from readCsv (different default separator) - Full ReadCsvOptions forwarding: indexCol, nRows, skipRows, dtype, naValues - 40+ unit tests covering all options, edge cases, and property-based round-trips - Interactive playground page with 9 examples Run: https://github.com/githubnext/tsb/actions/runs/25992061510 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

…caseWhen() — pd.Series.case_when() port Implements pandas.Series.case_when(caselist) (pandas 2.2+) as a standalone caseWhen() function. Applies an ordered list of (condition, replacement) pairs — first matching condition wins, unmatched rows keep original value. - src/stats/case_when.ts: full implementation with ResolvedBranch pre-extraction - Conditions: boolean Series, boolean array, or predicate (value, idx) => boolean - Replacements: scalar, Series, or array - 316 lines of tests (unit + property-based with fast-check) - 9-example playground page - Exported from src/stats/index.ts and src/index.ts Run: https://github.com/githubnext/tsb/actions/runs/26021661493 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
