This is the text pasted from Excel into BBedit, and then from BBEdit to here using "Paste as table".

This is text pasted from Excel as "Paste as List". The first one is just the first column (as bulleted list), the second one is all the columns (as enumerated list).

* distance
* 10
* 300
* 5280
* 240000

1. distance		angle	separation		
2. 10	feet	0.5	0.087266186	1.05	inches
3. 300	feet	0.5	2.617985571		feet
4. 5280	feet	0.5	46.07654605		feet
5. 240000	miles	0.5	2094.388457		miles

And, for grins, here's text pasted from Excel as "Paste as table rows". I copied the first two lines (the headers and the underscores) from one of the tables above, then copied everything else (i.e. starting at "10 feet" through the end of the table) from Excel.

| distance	|	| angle	| separation	|	|	|  
| --------	| -----	| -----	| -----------	| ----	| ------	|  
| 10	| feet	| 0.5	| 0.087266186	| 1.05	| inches
300	| feet	| 0.5	| 2.617985571	| 	| feet
5280	| feet	| 0.5	| 46.07654605	| 	| feet
240000	| miles	| 0.5	| 2094.388457	| 	| miles
