Adjust text overflow in cells

When Spreadsheet is rendered overflowed text inside the cell overlays subsequent cells until it meets non-empty cell. GroupDocs.Viewer provides a setting to configure the mode which will be used for rendering overflowed text:

To set the overflowed text to be hidden, set SpreadsheetOptions.TextOverflowMode of HtmlViewOptions class to HideText as shown in the example below.
To set the overflowed text to overlay subsequent cells until it meets non empty cell, set SpreadsheetOptions.TextOverflowMode of HtmlViewOptions object to OverlayIfNextIsEmpty. This is a default value.
To set the overflowed text to overlay subsequent cells even they are not empty, set SpreadsheetOptions.TextOverflowMode of HtmlViewOptions objectto Overlay.
To expand the cell width to fit overflowed text, set SpreadsheetOptions.TextOverflowMode of HtmlViewOptions object to AutoFitColumn.

NOTE: The same workflow is applicable for JpgViewOptions, PngViewOptions, and PdfViewOptions classes;
