I can click-drag the right side to resize the whole object, much as I did to resize an individual column. I can use the horizontal elevator (?) at the bottom of the sheet to slide the view area all the way to the right (the sheet appears to slide LEFT), so I will be able to see the right side of the table object. Its width would be the lesser of: the combined lengths of all of the table columns OR the max width of the sheet. The table object container is still very large. I can now adjust the individual columns to desired widths. All of the columns collapse to the width of the first column. From the pop-up menu, I select the entry 'Equal Column Width'. I can now right-click on the column header of the Longish column. The Longish one is more than 1/2 of the screen width, so I will manually shorten it by hovering my mouse over the column divider until it changed into a size-adjustment tool, and click-dragging the divider to shorten the column until is maybe 10% of the width of the visible screen. If the longish one is not the first column I will promote that field until it is the 1st column.

I can only see two columns, the rest extend far past the widest dimension the sheet shows. The Longish one is some 380 characters long. The Ludicrously long columns vary from over 1,000 characters to 32,767 characters. Four of the columns are LUDICROUSLY* long ones, and just a long-ish one. Now you can style them to required widths, adjust the row height and wrapping, etc.

Because the column was short, all of the rest of the columns should be visible on screen. The result should be that all of the columns are now the size of the short/re-sized column. From the pop-up menu, select 'Equal Column Length'. Right-click the column header for the shortest field. Resize the non-ridiculously-long column into some length less then the width of your screen ** DIVIDED BY the number of columns you have in the table. (If you do NOT have any column on screen that is not ridiculously long, you will have to insert a short field into the table, and promote it until it is the 1st column of the table.) If you have any column on screen that is NOT ridiculously long, then try the following steps. I would like to propose a different solution.
