> but the text editing required for OrgMode seems way too cumbersome

If you don't like key-chords then Emacs probably won't work for you, but just in case the video you watched wasn't clear about it, most of the markup is handled pretty much automatically by Emacs. Table creation and editing in particular works pretty much like in a graphical application. For example, if you want to create a table like

    | foo | bar | quux | qwerty |
    |-----+-----+------+--------|
    |  10 |  20 |   30 |     40 |
    |  50 |  60 |   70 |     80 |

All you need to do is insert the first row with the vertical bars to separate fields,

    |foo|bar|quux|qwerty

Then hit `C-c RET` and Emacs turns it into

    | foo | bar | quux | qwerty |
    |-----+-----+------+--------|
    |     |     |      |        |

with the cursor ready on the first cell under `foo`. Then you can just write the value and use tab to move to the next cell like in any spreadsheet program. Emacs will add new rows as needed and adjusts the table formatting automatically as you move to the next field (or when you hit `C-c C-c` if you don't want to move).

There are typical table editing commands available like moving, deleting and inserting columns or rows with [shift+]alt+arrows.
