- Select either 'tabl', if the 'a-sequence' should be formatted as a lower triangular matrix arrays , or 'tabf' for other (irregular) arrays.
- The output will have numbered rows and columns starting with the two 'off set' values. The default values are [0,0].
- The output caption will quote the 'Id-number' (with an 'A' in front). It will automatically be the OEIS A-number if this option is chosen for the 'a-sequence'.
- The 'a-sequence' input can be an OEIS A-number representing the tabl or tabf sequence as defined in OEIS under 'Keywords'.

If a sequence is typed in (use the pull down menue for 'a-sequence'), it should be a string of integers, enclosed by brackets [ ] and separated by commas (insensitive to blanks, no comma at the end), representing a tabl or tabf sequence.

- For 'tabf' arrays a 'shape sequence' is needed in addition to the 'a-sequence'. One can choose either the row lengths
or the step widths (the difference of the number of entries in consecutive rows, starting with the number of entries
of the first row). No negative numbers are allowed for row lengths sequence entries.

- The width of the output page entry (in number of characters) influences the row number of the output array (tabl or tabf type).
