spreadsheet

Hi, I'm trying to read a CSV file like this (;, delimiters):

A;B;C;D
1,1;2,2;3,3;4,1
1,1;2,2;3,3;4,1
1,1;2,2;3,3;4,1

What happens: semicolon from the first line does not become the main separator, the comma from the second line does and it breaks the file's logic.

Code that reads:

X.read(e.target.result, { type: 'string' })

Result

{
      A1: { t: 's', v:

This would be a nice little feature to have, Excel users are using this a lot.

It can also be difficult to see where the click/drag target exactly is. MUI’s Data Grid is a good example of explicitly showing the drag target: https://mui.com/components/data-grid/columns/#resiz
