printReportTable method

Future<void> printReportTable(DataReportTable reportData, String paperSize, { bool landscape = false, List<int>? columnFlexes, bool isView = false, bool use_highlighter = false, bool showSequence = false, })

Generates and optionally prints or previews a PDF table report.

This method builds a table-based PDF document using the provided reportData. reportData has tableData and tableSummary, and more... The layout can be customized using paperSize, landscape, and columnFlexes. The PDF can be previewed or printed based on the platform and the isView flag.

• On Web: Always previews the PDF.
• On Windows: If isView is true, opens a temporary file in the default viewer; otherwise prints directly.
• On Android/iOS/Linux/macOS: Opens or previews the PDF using the available tools.

Parameters:

• reportData: Contains the table data, summary, metadata, and other information to render the report.
• paperSize: Specifies the size of the PDF page (e.g., 'A4').
• landscape: If true, renders the report in landscape mode. Default is false.
• columnFlexes: Optional. Defines the flex values (column widths) for the table.
• isView: On supported platforms, controls whether to view or print directly. Default is false.
• use_highlighter: If true, applies a highlight style to the table. This will uses last column to highlight rows

Returns a Future that completes when the operation finishes.
