-In general methods in IronCalc use a 0-index base for the the sheet index and 1-index base for the row and column indexes.
-
-
-.. method:: evaluate()
-
-   Evaluates the model. This needs to be done after each change, otherwise the model might be on a broken state.
-
-.. method:: set_user_input(sheet: int, row: int, column: int, value: str)
-
-      Sets an input in a cell, as would be done by a user typing into a spreadsheet cell.
-
-      :param sheet: The sheet index (0-based).
-      :param row: The 1-based row index (first row is 1).
-      :param column: The 1-based column index (column “A” is 1).
-      :param value: The value to set, e.g. ``"123"`` or ``"=A1*2"``.
-
-.. method:: clear_cell_contents(sheet: int, row: int, column: int)
-
-      Removes the content of the cell but leaves the style intact.

-      :param row: The 1-based row index.
-      :param column: The 1-based column index.
-      :param style: A PyStyle object specifying the style.
-
-.. method:: get_cell_style(sheet: int, row: int, column: int) -> PyStyle
