This package is the browser-specific part mentioned in the environment-independent TBL package (You will find more information there about TBL in general). The package currently just contains a simple helper class to easily create a downloadable file.
First get the TBL-Browser package installed with a package manager of your choice. If you are using NPM just run the following command:
npm install @stenway/tbl-browser
Create a TblDocument and pass it to the static method download of the static TblDownload class. Provide a file name as a second argument:
TblDownload.download(TblDocument.parse("Table\nColumn1 Column2\nValue1 Value2\nEnd"), "Test.tbl")
