Dölj och visa rader och kolumner med JavaScript via C++
Kontrollera synligheten av rader och kolumner
Aspose.Cells for JavaScript via C++ tillhandahåller en klass, Workbook, som representerar en Microsoft Excel-fil. Klassen Workbook innehåller en WorksheetCollection som låter utvecklare få åtkomst till varje kalkylblad i Excel-filen. Ett kalkylblad representeras av klassen Worksheet. Klassen Worksheet tillhandahåller en Cells samling som representerar alla celler i kalkylbladet. Samlingen Cells erbjuder flera metoder för att hantera rader eller kolumner i ett kalkylblad. Några av dessa diskuteras nedan.
Dölja rader och kolumner
Utvecklare kan dölja en rad eller kolumn genom att anropa metoderna hideRow(number) och hideColumn(number) av Cells-samlingen respektive. Båda metoder tar rad- och kolumnindex som parameter för att dölja den specifika raden eller kolumnen.

Visa rader och kolumner
Utvecklare kan visa vilken dold rad eller kolumn som helst genom att anropa metoderna unhideRow(number, number) och unhideColumn(number, number) av Cells-samlingen respektive. Båda metoder tar två parametrar:
- Rad- eller kolumnindex - index för en rad eller kolumn som används för att visa den specifika raden eller kolumnen.
- Radhöjd eller kolumnbredd - radhöjden eller kolumnbredden tilldelad till raden eller kolumnen efter att ha visats.

Dölja flera rader och kolumner
Utvecklare kan dölja flera rader eller kolumner samtidigt genom att anropa metoderna hideRows(number, number) och hideColumns(number, number) av Cells-samlingen respektive. Båda metoder tar startrad- eller startkolumnindex och antalet rader eller kolumner som ska döljas som parametrar.
