Gets the index of the first non-empty cell within the row. This property allows for the identification of the starting point of data or formatting within a specific row of an Excel sheet, facilitating operations that depend on the row's content range.
Object.defineProperty(Row.prototype, 'firstCellIndex',
get: function()
)
A zero-based index of the row's first non-empty cell. If the row is entirely empty, this property may return a value indicating the absence of any cells, depending on the implementation.
The FirstCellIndex property is particularly useful for understanding the data distribution within a row. It can serve as a starting point for iterating through cells in a row or for determining the presence of data within specific row segments.
