Method 1 ： For the case of small amount of data , Consider the following methods ：

         Step one ： Set in the bottom cell of the first column ,B1 Indicates the first data position in the next column to be filled

         Step two ： Fill right first to the last column , Fill down again until the first column appears 0 until .

          Step three ： Delete redundant columns and 0, Just keep the first column .

Method 2 ： When the amount of data is too large or there are multiple tables to fill

         The method of manual filling is no longer applicable , At this time, the following function method can be considered , You need to ensure that all columns of the dataset have the same number of rows （ This function is verbose , Further optimization is needed , If the number of lines is not the same, you can refer to the following method ）：

         Step one ： Insert a new column before the first column , And set enough serial numbers .

         Step two ：  First, leave a row at the bottom of the data to be merged , At the same time, in the second column of data (C Column ) Enter the relative position of the second column of data cells to be copied in the lower space of the blank row （C1）, Finally, in this cell （C1） Enter the following function below , And set the parameters XX and NUM Back carriage return ：

=IF(ISBLANK(INDIRECT(ADDRESS(ROW(INDIRECT(XX))+1,COLUMN(INDIRECT(XX)),4)))=TRUE,ADDRESS(ROW(INDIRECT(XX))-NUM,COLUMN(INDIRECT(XX))+1,4),ADDRESS(ROW(INDIRECT(XX))+1,COLUMN(INDIRECT(XX),4))

function Used to determine whether the cell is empty . function Reference text format address C1 The data of . function Convert the specified rows and columns to cell relative addresses （C2）, function Output the number of rows and columns of cells at the specified address , The number NUM Represents the total number of rows in the dataset minus one , In this case NUM=5.XX Indicates the first reference address , In this case XX=C8.

The logic of the whole function is ： According to the given cell relative address , Judge whether the cell below it is empty , If not, the cell coordinates of the next grid will be output , If yes, the relative coordinates of the first cell in the right column of the column will be output . The offset value here can be set freely as needed .

 

          Step three ： double-click C9 The cross in the lower right corner is quickly filled . After filling, fill in B Column and starting position after filling B8 Input function at Then enter and fill quickly . Finally, keep the filled data in text format or numerical format , Delete extra columns and blank rows .

          If the number of rows in each column of the data set to be merged is not the same （ Here's the picture ）, Consider using the following replacement formula ：

NUM=COUNTA(INDIRECT(ADDRESS(1,COLUMN(INDIRECT(XX))+1,4)):INDIRECT(ADDRESS(10000,COLUMN(INDIRECT(XX))+1,4)))

The formula will NUM Value is replaced by the number of all non empty data in the right column under the current cell .
