You can put a formula in a cell, but it won't display the calculated value - you'll only be able to evaluate the formula and get the calculated value when you ask for it.

If you set the datatype of the column to FlexScript you can then enter a formula in FlexScript:

Table table = Table("GlobalTable1");
return table[1][1] * 10;

Then you can get the value out like this:

Table("GlobalTable1")[1][2]

That will execute the code in that cell and return the calculated value.

Unfortunately FlexSim does not support formulas in tables. You would have to write code somewhere outside of the table to update the table's cells. Or if you only need it on reset, you could use the Global Table's On Reset trigger.

If you'd like to see this feature added to FlexSim you could repost this as an Idea in the Development space. This allows users to vote on the idea and tells the developers which ideas are popular for future releases.

When you hit the Reset button and reset your model, the Global Table will fire its On Reset trigger. There are a few pick options available for clearing data in the table or you can write your own custom code. If you open the code you'll see that current references the table, so you can write code like:

Table current = param(1); //Table node
current[1][3] = current[1][1] * current[1][2];

And if you want to do this for all rows, add a loop:

Table current = param(1); 
for(int row = 1; row <= current.numRows; i++) {
  // Multiply columns 1 and 2 and store the result in column 3
  current[row][3] = current[row][1] * current[row][2];
}
