returns an error value.
For example, the following formula
=vlookup (E11, $C $: $D $6,3,0)
The query area here is only C, d two columns, and the specified returned column is 3, clearly beyond the query area range, Excel is dizzy, so it will show #ref!
Third: The lookup value is inconsistent with the data in the data source.
1. There are spaces.
You can double-click a cell to see if the last character has a space after it or to see it in the for
The array of Javascript arrays, both an array and a dictionary (Dictionary). Let's take a look at the use of arrays.
Copy Code code as follows:
var a = new Array ();
A[0] = "Acer";
A[1] = "Dell";
for (var i = 0; i Alert (A[i]);
}
Next look at the use of the dictionary.
Copy Code code as follows:
var computer_price = new Array ();
computer_price["Acer"] = 500;
In fact, this is a question that has been asked rotten, I think every computer has asked this question, because who buy a computer when they want to buy a better. I bought a computer when the same time, looking for a variety of data comparison, I came from the countryside, before college I do not know what the difference between computer and TV. To buy a good computer I looked up all kinds of information, after one or two weeks, I unexpectedly to the computer's various components have a certain
How do you count and match conditional data in an Excel table?
1, here still use the last table, you can see the marked area, we will statistics on these areas, the most commonly used function SUM, at this time can be written as "=sum ((a1:e11=" D ") *1)", and then the array operation by Ctrl+shift+enter
2, if you are familiar with other functions, we can also use the Sumproduct function, as shown in the figure. Enter "=sumproduct ((a1
The Array of Javascript is both an Array and a Dictionary ). Let's take an example to look at the Array usage of Javascript Array, which is both an Array and a Dictionary ). Let's take an example to see how to use arrays.
The Code is as follows:
Var a = new Array ();A [0] = "Acer ";A [1] = "Dell ";For (var I = 0; I Alert (a [I]);}
Next, let's look at the usage of the dictionary.
The Code is as follows:
Var computer_price = new Array ();Computer
