Select at least two values from the Arithmetic or Geometric column and then drag the values down with the lower right square.
The number series will get continued. Normally it would repeat the values.
Init JS code
function (pOptions) {
// Grid's number column parameters
pOptions.columns['ARITHMETIC'] = {
numberIncrementAutofill: true
}
pOptions.columns['GEOMETRIC'] = {
numberIncrementAutofill: true
}
return pOptions;
}
