Hi,

Is it possible to create an empty column using CalculatedColumn? Or how to create an empty column using KoolReport? This is because I want to insert a box in the column in the table.

Thanks.

Hi,

Just return empty string in Calculated column:

->pipe(new CalculatedColumn(array(
    "empty_column"=>"''";
)))

Tried the above and got this error:-

Message: number_format() expects parameter 1 to be float, string given

I tried to render the empty_column in my table but resulted in the above error. Need your help. Appreciate it.

Let do this:

->pipe(new CalculatedColumn(array(
    "empty_column"=>array(
        "exp"=>"''",
        "type"=>"string"
    ),
)))

I have a variable called gross_last_total from the code below. Could i apply this variable into empty_column of CalculatedColumn above? So, when i call empty_column in report.view, it shows me sum value of gross_last. Thanks.

->pipe(new AggregatedColumn(array(
            "gross_last_total"=>array("sum","gross_last")
        )))

You can use the gross_last_total directly. There is no need to copy it into the empty_column
