Whether this wrapper still refers to a live engine object.
The sheet name.
One past the last touched row (the used grid height).
One past the last touched column (the used grid width).
Number of charts on this sheet.
Number of pivot tables on this sheet.
Number of embedded pictures anchored on this sheet.
Number of sparklines on this sheet.
The print area definition text ("" if none).
Reference equality is the identity test — prefer a === b. This is retained only for
the rare cross-realm case where two wrappers describe the same handle by value. Reads the
raw index so comparing a stale wrapper never throws.
A readable identity for logs and diagnostics, never [object Object].
Rename the sheet.
The cell at (row, column), cached per address within the current edit epoch.
A rectangular range rowCount × columnCount with its top-left at (row, column).
The index-th chart on this sheet, or null if out of range.
The index-th pivot table on this sheet, or null if out of range.
Build a pivot table whose output lands on this sheet at (outputRow, outputColumn);
returns its wrapper, or null on failure. The source range and fields come from spec.
Set a column's width in logical pixels.
Set a row's height in logical pixels.
Freeze rows rows and columns columns at the top-left (0 unfreezes that axis).
Hide or show a column.
Hide or show a row.
Whether a column is hidden.
Whether a row is hidden.
Group rows [first, last] into an outline (optionally collapsed).
Group columns [first, last] into an outline (optionally collapsed).
Arm an AutoFilter over (r0,c0)-(r1,c1) (row r0 is the header row).
Set (or clear, when empty) a per-column contains-criterion, recomputing hidden rows.
Insert an encoded image (PNG/JPEG bytes) anchored (fromRow,fromCol)-(toRow,toCol) with
an explicit EMU extent; returns the image-store id (-1 on failure).
Add a sparkline in cell (row, column) over the data range (r0,c0)-(r1,c1). kind is
a SparklineKind; returns the sparkline index (-1 on failure).
Set the print area (which 0) or print titles (which 1) definition, e.g. "$A$1:$D$20".
Set the print-titles (repeat rows/columns) definition.
Set the sheet-protection flag mask (see the engine's <sheetProtection> bit layout).
Read a protection flag (bit 0 enabled, 1..15 the per-permission bits).
One sheet of a workbook. Reads are property getters off the model; Sheet.cell, Sheet.chart, and Sheet.pivotTable return cached wrappers whose identity holds within an edit epoch (a structural edit — a sheet/row/column add or remove — invalidates it).
