NewStreamWriter set buffer----Can I specify a buffer when streaming?

[pipi-king]

I want to ask if the buffer can be specified when writing down stream. When the NewStreamWriter is initialized, it wants to be like csv. Newwriter (b), because my structure is like this, and I want to specify buffer for streaming buffer.

type newReaderWriter struct {
c chan [][]string
b *bytes.Buffer
w *excelize.StreamWriter
f *excelize.File
rowNumber int
sheet string
}

After streaming writing, I can only write to my buffer through writeTobuffer, but there are only two sets of buffers, which makes no sense, and the memory of the file container will explode. Can I make a buffer when initializing?
