columnar
Ideally have the names in the first column of your data. Then select the column that has the names in it and the other columns. The active cell should be in the first column. Then go up to "Data" on the toolbar or the Sort and Filter options. You can select to sort alphabetically. If the Names are not in the first column you can use the Advanced sort option and choose it as the column you want to sort on when all of the columns of data are selected.
The name of the first element in a column typically represents the category or type of data being stored in that column. It sets the label or identifier for the information that follows in that column.

The top row of a table is called the header row. It typically contains column labels or headings that describe the data in each column below it.
Column Names.
Probably a heading.

It would use the data in the column as the basis for the sorting and sort the rest of the data.
Where a row and column intersect is a cell. To enter data into a cell, first select it and then type in what you want in the cell. Finally, press enter.
This is not a question, but my best guess to answer is: If the numeric data is too wide for the column, then increase the width of the column.
