Rows 1
The 'Rows 1' page in the Tools tab-pages contains commands to insert and delete rows in the current CPT File:
1/ Insert xx New Rows after Row aa
We choose the desired number of rows with the 'Quantity xx' control, and choose the Row number where we would like them to be inserted with the 'Row aa' control. The desired number of rows will be inserted after the existing row at the position specified. The inserted rows are all the standard 'Empty Row' that is used when a new CPT file is created. You can enter the Values and Colors directly, as described in the 'CPT File Window' help-section, or use the numerous tools in the Tools tab-pages to change or create value and color gradients.
2/ Insert New Rows every yy Metres, or Fraction, between the Start & End values in Row aa
Although you can add empty Rows and then create a gradient of their values with tools in the 'Values 1' tab-page, it is often convenient to combine adding and gradient-creation in one command. This tool does exactly that, by using the 'From' and 'To' values in a chosen row to set the start and end values of a gradient that has steps equal to the value entered in the adjacent box.
Imagine a row that currently has a 'From' value of '-1000' and a 'To' value of '-500'. If you use a value of '100' and click 'Go', the original row will be replaced by five rows, with From/To values of -1000/-900, -900/-800, -800/-700, -700/-600, and -600/-500.
3/ Delete xx Rows, Starting at Row aa
This command is fairly straight forward: just choose the number of rows that you wish to delete with the 'Quantity xx' control, and choose the first row that will be deleted with the 'Row aa' control. Click 'Go', and the desired number of rows will be deleted. Note that there is no 'Are You Sure? Y/N' dialog before the command operates, but you can always click the 'Undo' button to reverse the command.
You can also insert or delete rows by right-clicking any row to see the Context-Menu. This has two commands:
'Insert New Row Beneath This Row' - this inserts a single row beneath the right-clicked row.
'Delete This Row' - this deletes the right-clicked row without checking your action.
