Problem Description
The current toStyledString method uses a default StreamWriterBuilder, which has the following limitations:
Users cannot customize the output format, lacking flexibility
For decimal-type data, there is no convenient way to control the number of displayed digits
No functionality to adjust the indentation of output content
These restrictions significantly reduce the practicality of toStyledString in scenarios requiring precise control over string output styles (such as data display, logging, etc.). Users have to write additional formatting logic, increasing development costs.
