I use the Tables Generator web site as a starting point. (Note that I'm not affiliated with it.)
The unmodified result of creating a 5-row by 8-column table and filling it with the raw data from your example, plus the column/row names, is this:
+---+-------------+-------------+-------------+-------------+-------------+-------------+-------------+
| | A | B | C | D | E | F | G |
+---+-------------+-------------+-------------+-------------+-------------+-------------+-------------+
| 1 | Cell 1 | Cell 2 | Cell 3 | Cell 4 | Cell 5 | Cell 6 | Cell 7 |
+---+-------------+-------------+-------------+-------------+-------------+-------------+-------------+
| 2 | Cell AA | Cell BB | Cell CC | Cell DD | Cell EE | Cell FF | Cell GG |
+---+-------------+-------------+-------------+-------------+-------------+-------------+-------------+
| 3 | 0.800975839 | 0.069498939 | 0.928547206 | 0.687179413 | 0.049817769 | 0.146646454 | 0.453482289 |
+---+-------------+-------------+-------------+-------------+-------------+-------------+-------------+
| 4 | 38 | 23 | 31 | 55 | 68 | 95 | 75 |
+---+-------------+-------------+-------------+-------------+-------------+-------------+-------------+
I then manually modify it to look like this:
| A | B | C | D | E | F | G
---+-------------+-------------+-------------+-------------+-------------+-------------+-------------
1 | Cell 1 | Cell 2 | Cell 3 | Cell 4 | Cell 5 | Cell 6 | Cell 7
2 | Cell AA | Cell BB | Cell CC | Cell DD | Cell EE | Cell FF | Cell GG
3 | 0.800975839 | 0.069498939 | 0.928547206 | 0.687179413 | 0.049817769 | 0.146646454 | 0.453482289
4 | 38 | 23 | 31 | 55 | 68 | 95 | 75
