Hi @PraveenkumarR3390: Hope you have a table configured using the pagelist property and each column of the table you have added corresponding property to be shown and now all the columns are shown as editable because of your table configuration (row editing as inline). If this is the case, click on the cells (columns) which you want to make as read only which will open the cell properties. In the presentation tab, change the edit option to read only always for the required cells.

This is the same what @RaghavaP5161 explained.

Hope this helps. If this is not the case, please share additional details on your table configuration (may be a screenshot without confidential data) to check further

Thanks.
