Answer 1

Use the PowerFX Collect() function here.

1. OnSelect of the "Add Row" button:

Collect(colRecords,
    {
        id: CountRows(colRecords) + 1,
        join: chkJoin.Selected.Value,
        andOr: chkAndOr.Selected.Value,
        type: ddType.Selected.Value,
        operators: ddOperators.Selected.Value,
        valueResult: ddValue.Selected.Value
    }
)

Where all the values on the left side of the colons above are the names of your columns and the values on the right side are the names of your controls.

2. Ensure the Gallery Items property is set to colRecords
