The main issue with your code was that you set rownames=F in the datatable() function, which means that the rownames are not used as filter criteria. Instead, the input$tabelle_rows_all uses the rownames to filter the table. To fix this, you should remove the rownames=F argument from the datatable() function and let it use the default behavior of using the column names as the filter criteria. Here is the corrected code:

Understanding NSDecimalNumbers and Their Limitations NSDecimalNumbers are a type of numeric data type used in Objective-C to represent decimal numbers with high precision. They were introduced in macOS 10.4 Tiger as part of the Foundation framework, providing a way to handle decimal arithmetic that is more accurate than the traditional float or double types. At their core, NSDecimalNumbers are based on the IEEE 754 floating-point representation standard for single and double precision floating point numbers, but they also include additional features such as support for fractions and arbitrary-precision arithmetic.
