How to use DeSeq2 to process salmon quantification files

[authentic-zz]

Hi, The data I currently have is quantified by salmon. But it was organized into a text file (row name is the ID of the gene, and the column name is the sample name), which seems to be different from the file input by tximport package. How can I use tximport package to process this file and use DESeq2 to further analyze it? For those who do not have a good knowledge of R, this change is very confusing. The picture below is part of the data. If anyone could generously provide a solution, I would be very grateful.
