Loop through list to copy batches of like values

I'm trying to copy batches of rows, based upon one column's values.

The worksheet looks like this (sorted by the first column):

A  5  blue  
A  6  yellow  
B  3  red  
B  2  blue  

The loop has 3 primary steps:

1. Copy all rows beginning with a value, e.g. rows 1-2, which both begin with "A"
2. Paste rows into an email (I know how to do this)
3. Move to the value, B, and copy all rows starting with B

I won't know the 开发者_高级运维values of Column A, as they will change each time. Is there a way I can still write this loop?

2 possible approaches:

1: Rather than thinking of it as copying all the "A" rows at once, have a build string that you add to for each row, and then when you hit a new value for the first column, flush the build string into the email. That way its a single loop with a condition check in there.

2:

• Maintain a startPos. set it to 1.
• Loop through first col till value changes.
• Copy startRow - currentRow - 1 to email.
• set startPos = currentRow.
• Repeat.
