Just found a bug while building a table with 1st column made of the lines output by ls -1. That means, in the beginning there's only 1 cell in each row, and if adding additional columns in other rows, the delimiter ('|') is taken as-is. No difference if the table has a header line or not, or if that one cell is following a '|'.

Examples:

2 cells each

table with header

1	2
one	two
a	b

table without header

1	2
one	two
a	b

2 cells, 3 later

table with header

1	2
one	two
a	b	c

table without header

1	2
one	two
a	b	c

1 cell, 3 later

table with header

1
one | two
a |b | c

table without header

1

one | two

a |b | c

1 cell (ended by delimiter), 3 later

table with header

1
one	two
a	b	c

table without header

1
one	two
a	b	c

1 cell (line starts with delimiter), 3 later

table with header

|1
one | two
a |b | c

table without header

|1

one | two

a |b | c

1 cell (line starts with SPC + delimiter), 3 later

table with header

	1
one	two
a	b	c

table without header

	1
one	two
a	b	c
