You won't ever get the same look in notepad or wordpad that you would see in a table. The table automatically lines up the data in rows and columns. In notepad or wordpad, all it sees is data, space, data, space, etc. There is no mechanism to line up into columns. You could force the line up if you inserted a tab character between each data value. then you would have data, tab, data, tab,... Notepad would see the tab and move to the next tab mark, thereby lining up the columns. However, if one of the data fields or headers have more characters than the next tab mark, a misalignment could take place. If you want to see things lined up, use a spreadsheet instead of notepad.
On your second issue, the first column (column 0) and first row (row 0) are he
ader information, like "Block 1" and "Amplitude". When reading the file, these values cannot be converted to a number, so you will see a 0 in all columns of the first row and all rows of the first column. When you delete the first row and first column, you are eliminating the headers and get the correct data. Column 6 has zeros because there is no data in column 6. There is a column 6 becasue you wrote the file with a space before CYCLE. This created a column header with no data in that column. Your data for Cycle fell under the column with a space for a header. You do not need that space before CYCLE. Take it out. (Don't worry about it not lining up in a text file, it won't) Then you won't need to delete column 6 because there won't be any column 6. After deleting column 0 (Block#), you will be left with columns 1 through 6 shifting to occupy columns 0 through 5 to fill in for the deleted column.
