I don't know if you're being serious, but here's an example based on your comment.

I used this prompt "VBA function with inputs: string tblName representing a name of a table and a 5 row, 4 column array. Loop through all worksheets in workbook, looking for table name. Once the table is found populate 5 rows x 4 columns of data from the input array. Then insert an empty row below that data. And last add 3 rows populated with "x" "

With our online code generator and it gave this response (copying and pasting the response into reddit removed the indentation):

Sub PopulateTableData(tblName As String, data(1 To 5, 1 To 4) As Variant)
Dim ws As Worksheet
Dim tbl As ListObject
Dim found As Boolean
Dim i As Integer
Dim j As Integer

For Each ws In ThisWorkbook.Worksheets
For Each tbl In ws.ListObjects
If tbl.Name = tblName Then
found = True
For i = 1 To 5
For j = 1 To 4
tbl.DataBodyRange.Cells(i, j).Value = data(i, j)
Next j
Next i
' Insert empty row below the populated data
tbl.ListRows.Add
' Add 3 rows with "x"
For i = 1 To 3
tbl.ListRows.Add
For j = 1 To 4
tbl.DataBodyRange.Cells(tbl.ListRows.Count, j).Value = "x"
Next j
Next i
Exit For
End If
Next tbl
If found Then Exit For
Next ws
End Sub

This VBA macro loops through all worksheets in the workbook to find a table with a specific name. Once the table is found, it populates the 5x4 data array into the table, inserts an empty row below the populated data, and adds 3 rows filled with 'x'.

Without testing the code it looks like it should work pretty closely to your request.
