Hi,
You can add your own routine to do this.
1. Click Code Builder button to open code builder
2. Open LabTalk ogs file: <User File Folder>/Custom.ogs
3. Copy the script below and paste it to [Main] section
4. Click Custom Routine to add columns
//type -b $General.Userbutton;
//add two new columns
wks.nCols = wks.nCols + 2;
//set the first new column as X
wks.col = wks.nCols - 1;
wks.col.type = 4;
//set the second new column as Y
wks.col = wks.nCols;
wks.col.type = 1;
//select cells
worksheet -sl $(wks.nCols - 1) 1 $(wks.nCols) 1;
//merge long name
menu -e 35045;


Hope it helps.
Regards, Yuki
