Original GitHub issue: https://github.com/rivo/tview/issues/340

The result of the tabstop replacement should be an integer multiple of tabsize. Instead of simply replacing tabstop with an equal amount of space.

For example, the result of replacing "abc\tdef" should be "abc<space>def" instead of "abc<space><space><space><space>def".

Hope to fix this problem.

The handling of tabs in tview is not as it is in other applications. See here:

Tab characters will be replaced with TabSize space characters.

Granted, this is not the original meaning of a tab. It's a very simple approximation. But I don't see proper tab handling implemented any time soon. It's extremely difficult to make it work, especially with Unicode, wide characters, word-wrapping etc. So for the time being, it will remain as it is.

I'd be open to changing TabSize to 2, though, if enough people agree.

I stumbled upon this issue @rivo debugging tabs in virtual table. For example in this

func (d *TableData) GetCell(row, column int) *tview.TableCell {
    return tview.NewTableCell(d.lines[row])
}

if the text added into the table cell contains one or more leading tabs then they are displayed as if TabSize=0.
