function tblSetCellAction(const Table: ITBL; Row, Col: Integer; ActionHandle: Cardinal; Mode: THighlightMode): LongBool; stdcall;
function tblSetCellDashPattern(const Table: ITBL; Row, Col: Integer; Side: TCellSide; Style: TLineCapStyle; const Dash: PSingle; NumValues: Cardinal; Phase: Single): LongBool; stdcall;
function tblSetBoxProperty(const Table: ITBL; Row, Col: Integer; PropType: TTableBoxProperty; Left, Right, Top, Bottom: Single): LongBool; stdcall;
function tblSetColOrRowSpan(const Table: ITBL; Row, Col, Value: Cardinal; IsColSpan: LongBool): LongBool; stdcall;

Purpose. tblSetCellAction attaches a clickable action (an already-created action handle, Actions & Named Destinations) to a cell with a highlight mode. tblSetCellDashPattern sets a per-side dashed-border pattern. tblSetBoxProperty sets per-side box (border) geometry — genuinely real for all four sides independently. tblSetColOrRowSpan merges adjacent cells horizontally or vertically.

Description. All four are plain, real, bounds-checked field setters, each storing directly into the corresponding TTableCell fields (HasAction/ActionHandle/ActionMode; HasDash/DashSide/DashStyle/DashVals/DashPhase; HasBoxProp/BoxPropType/BoxL/BoxR/BoxT/BoxB; ColSpan/ RowSpan). tblSetCellDashPattern's Dash/NumValues array is marshaled into a real Pascal array before storage (no truncation or data loss observed). tblSetColOrRowSpan's IsColSpan selects which of the cell's two span fields (ColSpan vs. RowSpan) Value writes to — a single call sets exactly one axis, not both.

Parameters.

Parameter	Description
`Table`	Target table handle.
`Row`, `Col`	Target cell coordinates.
`ActionHandle`, `Mode`	(CellAction only) The action and its click-highlight visual mode.
`Side`, `Style`, `Dash`, `NumValues`, `Phase`	(DashPattern only) Which border side, the dash cap style, the dash-length array, and the starting phase offset.
`PropType`, `Left`, `Right`, `Top`, `Bottom`	(BoxProperty only) Which box property, and per-side values.
`Value`, `IsColSpan`	(ColOrRowSpan only) The span count, applied to either `ColSpan` or `RowSpan` depending on `IsColSpan`.

Return value. True if Row/Col are in range for all four functions.
