1-9: Add parameter validation and extract options interface.Consider adding validation for the table parameter and extracting the options interface for better reusability.
+interface TableToCSVOptions { + separator?: string; + header?: string[]; + columnSelector?: string; + transformGtLt?: boolean; +} + function tableToCSV( table: HTMLTableElement, - options: { - separator?: string; - header?: string[]; - columnSelector?: string; - transformGtLt?: boolean; - } = {} + options: TableToCSVOptions = {} ): string { + if (!(table instanceof HTMLTableElement)) { + throw new Error('Invalid parameter: table must be an HTMLTableElement'); + }
28-36: Optimize DOM queries and array allocations.Consider caching selector results and using more efficient array operations.
- const rows = table.querySelectorAll("tbody tr"); + const tbody = table.querySelector("tbody"); + if (!tbody) { + throw new Error("Table must contain a tbody element"); + } + const rows = tbody.rows; rows.forEach((row) => { - const columns = row.querySelectorAll(columnSelector); - const rowData = Array.from(columns).map((col) => formatData(col.textContent || "")); + const columns = Array.from(row.querySelectorAll(columnSelector)); + const rowData = columns.map((col) => formatData(col.textContent || "")); if (rowData.some((data) => data.trim() !== "")) { csvData.push(rowData.join(separator)); } });

1-45: Overall implementation looks good with room for improvement.The TypeScript implementation successfully replaces the jQuery plugin with a more modern, type-safe approach. The code is well-structured and handles the core functionality effectively.
Consider adding comprehensive unit tests to verify:
- Header validation
- Empty row handling
- HTML entity transformation
- Edge cases with malformed tables
Would you like me to help generate test cases for these scenarios?
19-26: Add header length validation.Consider validating that the header length matches the number of columns in the table to prevent data misalignment.
if (header.length > 0) { + const columnCount = table.querySelector('tbody tr')?.querySelectorAll(columnSelector).length ?? 0; + if (header.length !== columnCount) { + throw new Error(`Header length (${header.length}) does not match column count (${columnCount})`); + } csvData.push(header.map(formatData).join(separator)); } else {
