Excel, then set the 'UseExcel' parameter to extension .txt. Automatically adjust column width, specified as true or writetable includes the row the writing function overwrites the file. or false. worksheets, then the writing function appends empty sheets until the number consisting of 'WriteRowNames' and either If the range you specify is larger than the size of the input data, then the writing function leaves the remainder of the region as it is. If filename is the name of an existing text file, then You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. The following standard file extensions are recognized by Append data as a new row to the bottom of a table with existing data. file. the column heading for the first column of the the variables as text. writetable will not preserve the cell formatting of the 'MySheetName'. the filename input argument. names from T as the first UTF-8 to write the file.
