When you insert a table in Word, a border is automatically created for each cell in the table. This border is a single line, one-half point in weight. Unfortunately, Word provides no way for you to change the default line width you use when creating the table. While it is true you can pick a line width in the Borders and Shading dialog box, this weight is reset to one-half point when you insert a new table.
If you want some other line width, such as three-quarters of a point, you have a problem. You must manually select any new table and format the borders, so they are the desired width. If you work with lots of tables, this can quickly become a hassle. You could, of course, create a table style, but applying a table style can give uneven results if all you want to do is change the line width or if you are working with a document where there has been a lot of explicit formatting applied to the tables.
Perhaps the best way around this problem is to write a macro. Even though this may not be the most ideal solution, it certainly is easier than manually changing every table in the document.
The following macro, FixCellBorders, steps through every cell in every table in your document and makes sure the minimum line weight is three-quarters of a point. It does this by checking out the current line settings, and then making the adjustment only if necessary.
Sub FixCellBorders() On Error Resume Next ' Work through all tables in document For Each objTable In ActiveDocument.Tables ' Work through all cells in each table For Each objCell In objTable.Range.Cells ' Work through all borders in each cell For Each objBorder In objCell.Borders ' Check if line weight is less than 0.75 pt If objBorder.LineWidth = wdLineWidth025pt _ Or objBorder.LineWidth = wdLineWidth050pt Then ' too thin, change it objBorder.LineWidth = wdLineWidth075pt End If Next objBorder Next objCell Next objTable End Sub
As you can imagine, the macro is not terribly fast since it looks at all four borders for every cell in every table of your document. The advantage, however, is that the macro will only modify the weight of any cell border that is at one-quarter or one-half point. This means that any manual formatting you have done for different line widths will not change.
If you are looking for a bit faster macro, the following (FixTableBorders) will do the trick. Instead of looking at individual cells, it works on entire tables. The difference, however, is that it resets every border of every table to three-quarters of a point, using a single line. If this fits your needs, however, it is definitely the easier (faster) way to go.
Sub FixTableBorders() On Error Resume Next For Each objTable In ActiveDocument.Tables With objTable With .Borders(wdBorderLeft) .LineStyle = wdLineStyleSingle .LineWidth = wdLineWidth075pt End With With .Borders(wdBorderRight) .LineStyle = wdLineStyleSingle .LineWidth = wdLineWidth075pt End With With .Borders(wdBorderTop) .LineStyle = wdLineStyleSingle .LineWidth = wdLineWidth075pt End With With .Borders(wdBorderBottom) .LineStyle = wdLineStyleSingle .LineWidth = wdLineWidth075pt End With With .Borders(wdBorderHorizontal) .LineStyle = wdLineStyleSingle .LineWidth = wdLineWidth075pt End With With .Borders(wdBorderVertical) .LineStyle = wdLineStyleSingle .LineWidth = wdLineWidth075pt End With End With Next objTable End Sub
